These are our recommended drop in solution for boosted aluminum head engines from the 2.8 to the 3.5 (Non VVT) engines, and naturally aspirated LZ engines. Good for 20+ psi of boost on our stage 2 turbo cam and for LZx applications, anything NA up to .600" lift will do. Boosted LZ applications can also make use of this spring and likely handle quite a bit of boost as well, though we have a double spring option that might be worth checking out.

• 135# @ 1.800"

• 348# @ 1.175"

• 340# Spring Rate

• 1.100" Coil Bind

• Set of 12

After years of using a variety of springs for just about every application, we have come to realize this spring is the only one you need outside of boosted applications. Drag racing, road course, circle track using high lift/high duration cams work flawlessly. .600" lift capability without modifying the heads. Stock seat/seal compatibility.

We have a range of cams that cover most applications, but not all. Whether you are using our cam selection service to dial in for your specs, or have the lobes and centerlines, this is the option to make it happen. If you are supplying the specs, please provide the lobe numbers and centerlines.

Please allow 4 weeks (typical turn around time) or more for custom cams.

Studs should be installed hand tight and the nuts torqued down 80 foot pounds with ARP lube. These are proven in both high output applications, and high temp, such as demolition derby when paired with our Cometic MLS head gasksets.

GM Oil Bypass Valve is a simple piece to remove and replace when you have a block cleaned for a rebuild.

ARP rod bolts/nuts for the 60V6 2.8, 3.1, 3.4, 3100, 3400, and 3.4 DOHC connecting rods. These are an excellent upgrade for the money, especially when compared to the cost of new stock replacement rod bolts. Cutting the rod caps and resizing the big end is required.     

A premium grade 8740 alloy chrome moly steel is used to manufacture ARP® High Performance connecting rod bolts. This material is heat-treated to provide a tensile strength in the 200,000 psi range, which is substantially stronger than the OEM bolts. Cycle testing shows ARP® High Performance rod bolts to be nearly five times more reliable than stock bolts

We have 2 spring seat options for the Gen 2 2.8/3.1 and Gen 3 3100/3400/3500 LX9

• 1.300” OD, .570” ID, .060” thick for our Stage 3 springs, and any other LS style spring.

• 1.510” OD, .570” ID, .060” thick for our Stage 2 springs.

The Stage 3 spring seats are a drop in fit, and keep the LS style spring centered.

The Stage 2 spring seats are a perfect springs, but with a 1.510” OD. This will fit most of the stock spring pockets, but some are a little too small. A machine shop can open them up, or with enough patience and skill, manually with a die grinder or dremel tool.

While we have the seats made for the Stage 2 springs available, the easier and more common option would be to use the stock seat/seal. We sell them under the Valve Seal listing, calling them Top Hat style. Please note, if any spring seat machine work to increase the spring install height is performed, the Top Hat style will not work.

Some other notes.

The seats for the Stage 3 springs work with the Stage 2 springs as well but won’t keep the spring perfectly centered to the valve like the seats made for them would be. If you have to cut the spring pockets to increase the install height, increasing the diameter for a few seats won’t cost any more.

This stock style of seat/seal does not fit the Stage 3 springs very well. Yes, you can force them in place but the added friction is not good, and we do not recommend this.

We stock replacement press fit valve stem seat/seals and press fit seals for all the aluminum head pushrod 60V6 engines.

• .500” ID for the LZ4/LZ9 heads

• .520” for the Gen 2 and 94-99 3100

• .553” 2000+ 3100 and all 3400/3500 LX9

Stock replacement seat/seal combo is recommended for stock builds, Stage 2 springs on the .520” and .553” heads. Stage 3 springs on the .500” heads.

Press fit is used for aftermarket seats such as those for using stage 3 springs on the .520” and .553” heads, or double springs on the .500” heads.

All seals are Viton for best performance and durability.

We have purchased every available chain and none of them compare to the OEM quality of the MORSE chain. Nearly every other company uses the same chain Cloyes includes in their kit. It might be ok for a stock engine with stock valve springs and grocery getter use, but if you want something that takes a beating and doesn’t stretch in under 30k miles, this is the set you want.

ATTN Gen 1 60V6 owners. The factory chain is no longer made for your original timing gears. No testing has been done with the Gen 1 parts to compare, but given the track record for the newer engines, we will stick with this Gen 2 set as a recommendation for your Gen 1 engine.

Set Includes

• Crank Gear

Stock gen 2 rockers are stamped steel 1.5:1 non roller fulcrum or tip rockers. As stamped steel goes, they may or may not really be 1.5:1. These comp roller tipped rockers are stronger (8620 chromemoly steel) and much more precise than stock..  They were designed for the iron head setup, which you can use their rocker studs to get an adjustable rocker arm setup. For gen 2 aluminum head 60V6s, you can reuse your stock nut with a washer on top, on the stock stud and just torque it down. 

Set of 12 Manley 4140 chromemoly steel retainers and machined keepers, made in the USA. 13% lighter than stock. Manley shaved the top of the retainer to be flush with the keepers, which gives more clearance between the retainer and the rocker arm. 

These are for beehive springs. Gen 2 MPFI Aluminum Head owners will need to change to a beehive spring to use these retainers.

Comp Cams adjustable pushrod for the flat tappet engines using pushrods longer than 6.200" length. Each rotation is .050" and is marked for easy measurement without a caliper.

Also used for LZ4/LZ9 VVT Delete / Performance cam installation

Most, if not all of the flat tappet camshafts made for the 60V6 engines were designed for use on the iron head engines. This is fine for budget builds, with the Comp 260H grind being the overwhelming favorite for naturally aspirated use. What those cams lack however is valve lift, and open and close events better suited to the much improved flow of the Gen 2 and especially Gen 3 engines.

Based on our roller cam results for the same top end setups, these flat tappet versions work best with the Gen 3 SFI cylinder heads. If you have a complete Gen 2 engine, the RPM range won't be as high due to the limitations of the intake manifolds/airflow. That is another topic of its own but just be aware that a cam with a powerband over 6k RPM isn't going to make your Gen 2 have power to 6k where the Gen 3 top end would.

All of the cams listed work great with our stage 2 beehive springs. New flat tappet lifters are required and not included with this camshaft listing. Pushrod lengths should be measured once the new cam is installed to determine optimal length for lifter preload.  

If you have specs you are looking to get, please fill out the form with those. Otherwise, the heads and application are enough for us to give you a recommendation. If you supply specs, we will verify with what we have available before making it happen.

3/8" Thick Mild Steel Header Flanges

Designed and made by 262 Plasma for the aluminum head 2.8, 3.1, 3100, 3400, and 3500 LX9 engines. 1 5/8" round ports with no overlap into the ports with the primary tubes installed. Easy access to the spark plugs without removing the headers.

We cut the stock MLS exhaust gaskets into individual ports using tin snips when using these flanges. (not included)

Headers can represent a sizable investment, so you'll want to keep them securely attached. In addition, exhaust leaks can cost you power and even cause damage to your vehicle. ARP has the answer, in the form of their stainless steel header studs. They're made from premium 300 stainless steel, which is rated at 170,000 psi tensile strength. That's much stronger than Grade 8 steel. These studs are also highly corrosion and heat-resistant, for long service under the toughest conditions, and they're polished to a mirror-like shine. This kit includes 12 studs, plus premium-quality washers and 12-point nuts.

Torque spec is 33 ft lbs

Bi-metal rod bearings will handle more than the stock connecting rods can take. These are for the 2” journal engines (2.8-3.5l). LZx engines use 2.25” journal rod bearings.

Since 2004, we have used tri metal bearings for everything as it was the best option available. Over the last couple decades, bi-metal has become the norm, with improvements being made along the way. Now, these bi metal aluminum bearings are considered to be almost as good as the tri metal for strength. That is good news, both for the price, and for anyone looking to build a high performance 60V6.

These SBC cam bearings are a direct replacement, and will spread the load across the entire cam journal, unlike the stock bearings. Bi metal to support the roller cam profile and the load of higher spring pressure associated with performance cams. Regular SBC cam bearings are not designed for roller cams with stiff springs, and will crush when used with stiffer than stock valve springs.

Teflon coated as an extra layer of protection for oil pressure loss. We run these in our race engines for what little they add to the overall cost of a build.

It has been brought up more than once, so to avoid confusion, the original bearings have 2 holes in one end bearing, while these do not. This hole is there for cams with a lobe for a fuel pump pushrod. We do not need this, therefore, we do not drill the bearing for it.

Each set has 2 inner and 2 outside bearings.

Multec 2 style OEM 28# injectors are our go to for naturally aspirated builds. Drop in for 2000-2005 3100/3400 engines, or contact us for the connectors that can be cut/spliced onto your 1999 and older Multic 1 harness.  

Multec 2 itself was a redesign to reduce the potential for cloggin that the older style were more suspectable to.  Rated @ 55PSI. The 1999 and older engines used 43 psi, which equals ~23# injectors.

Sets will flow +-1% variance max.

Based on a stock 2004-2006 3500 LX9 with the 1227730 ECM, using a 3400 fuel rail, 2000+ fuel pressure regulator at 55psi, and 28# injectors.  All manual transmission setups should be a plug and play deal, while the automatic may need some tweaks to fine tune.

New Alignment Pins (Dowels) for 60V6 cylinder heads, sold as a set of 4. 

Custom length pushrods will give you the most from your camshaft upgrade due to the optimal preload on the lifter, and the thicker .083" wall thickness. Made from heat treated 4130 chromoly steel coupled with heat treated pushrod ends, and good for up to 700 pounds open valve spring pressure. When ordered with a camshaft, we measure the cam itself to determine the proper length. The additional comment field is there to tell us if you have milled the heads or the deck surface of the block, or if you know what lengths you need after doing your own measuring. An adjustable length pushrod can be used to determine the optimal length once the cam is installed as well.

Hardened pushrods option available for use with pushrod guideplates (Gen 1 and 2 motors). Hardened pushrods should have the pressed in tip installed on the lifter side.

We have some sizes in stock. Turn around time varies depending on supplier/market demand...aka race season. Typical 1 week turn around, up to 4+ at times.

There are 2 versions of the Gen 3 60V6 Timing Sets. 94-99 used the same chain as the older Gen 2 engines, but with a different cam gear for the new roller cams. The 2000+ sets used a narrower chain with more links to address noise. Both sets are compatible across the board.

The strongest option we have is the older 94-99 style with a MORSE chain. This chain uses a damper like the 3100,3400, and 3500 LX9 use. Our sets only use the OEM MORSE chain. The aftermarket chains would stretch more in 30k miles than the OEM did in 100k+

The 00+ style has its advantages, and has yet to fail us racing. Its quieter, and allows the option to replace the stock damper with a tensioner. This keeps the engine in time for a long long time, but also increases friction. More testing will need to be done to tell if there is a performance difference between the 2, new, and after a race season or 2. One of these setups lasted 7 seasons of circle track without the best maintenance in those later years, using the tensioner. We are calling this the WOT-Tech version of the 2000+ Style timing set (MORSE timing chain with tensioner)

The budget version of the 2000+ timing set uses the newer cloyes chains and a damper like stock.

Using the latest GM revisions, our performance chips not only increase performance, but also enhance drivability.

Our 7X External Crank Trigger kit will allow you to installed an LX9 3500 V6 into any older 60V6 and retain the stock computer.

Our fully machined throttle body adapter lets you install a 96-99 Oldsmobile Aurora 4.0 Throttle Body onto a 3500 LX9 or 3500/3900 LZ upper intake. Throttle body gasket included.

We have designed an adapter to use the 65mm TB found on the Oldsmobile 3.5 DOHC. Bolting it to the manifold (3100, 3400 or 3500 LX9 / 3500/3900 LZ engines, both bolt patterns and sets of bolts are included) is no problem, but attaching the throttle cable bracket will be a DIY project. You will need both gaskets for the 3400 (FelPro 61304 for the TB to Adapter and FelPro 60983). The 3500 upper will need silicone to seal the adapter to the manifold instead of a gasket. We modify the 3400 gasket for the 65mm bore if you buy it with the adapter.

You can find this throttlebody on the 1999-2002 Oldsmobile Intrigue and 2001-2002 Oldsmobile Aurora.

Brand New, Limited Supply! These have new sensors and the larger vacuum port intact with a vacuum cap.

Upgrade to a 65mm throttle body for better throttle response and more power.  Can be used on the 3100, 3400, and 3500 upper intake with our WOT-Tech LX5 TB Adapter. We also offer a package that includes a modified cable bracket for either the 3100/3400 or 3500 upper intake.  (currently sold out of cable brackets)

The stock 3100 Throttle body is 52mm. Stock 3400 s 56mm. While this seems like a small difference, it will equal a very noticable difference once installed on a 3100 engine. Sold as a bare throttle body with plate, so you will need to swap your stock sensors to the new throttle body, as well as your stock linkage/shaft. No cutting required though torx bits and a hammer will be necessary to remove the sensors and stock plate. The hammer is used to tap the shaft out once the plate and TPS are removed.

Based on a stock 2000+ 3400 swap into a 5 speed Fiero, with the 1227730 ECM.  All manual transmission setups should be a plug and play deal, while the automatic may need some tweaks to fine tune.  2000+ injectors and 55 PSI fuel pressure required.
