There are three types of LS engines TSEC builds. Mildly modified stock engines, mild performance off-road, and more serious engines built with a new block, and all new parts.
While pricing is shown, the final price may vary due to the many potential options that are available.
On the more extreme engines it is strongly recommended that the engine is started and dyno tuned before shipping to make sure it runs correctly. So final tuning for the local air conditions and chassis maybe required.
Various super are also available.
I have tried to show as many parts options as I can, but knew products for the LS motor are coming out all the time.
I am making available crankshaft kits to complete turnkey engines. reveiw the parts below to see where the money goes and what the options are.
NEW GM LS7 crate motor $13,600
Complete Stroker Engine Finished Motor - PCM etc $18,000 See Details
LS3 + Hot Cam = Loads of Fun The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-revving 376-cid combination that represents generations of small-block V-8 development and engineering.
Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!
The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-revving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.
The GM Performance Parts engineers picked the LS Hot Cam (P/N 88958733) to take the LS3 to the next level. This cam specs out with .525" intake and exhaust valve lift. Duration (@ .050") is 219° intake and 228° exhaust, which allows for a dramatic increase in power. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it.
What’s the difference between LS1 / LS6 blocks and the new LS2 aluminum block?
• LS2 blocks feature a 4.00” bore, LS1 / LS6 have 3.888”
• Crankshafts, connecting rods, pistons and cylinder heads are interchangeable between LS2 and LS1 / LS6 engines
• LS2 cylinder heads are made from the same castings as the LS6
• LS2 blocks have the knock sensor on the side of the block compared to LS1 or LS6 block that have it in the lifter valley.
• The cam sensor has been moved to the timing cover (requires use of LS2 cam gear)
• LS2 knock sensors send a different signal type and are not interchangeable with LS1 / LS6
• LS1 computer will control LS2 engine, except for the knock sensors.
Scat can make any crank to match any combination to meet your specific engine. Most cranks require a 3-4 week deliver time. All crankshafts are made right here in the U.S.A by Scat. LS cranks are available in 4.00" 4.125' and (4.250" not recommended)

APO31LMG6125 4.000 4340 Steel LS1 Callies Magnum Crankshaft
APH31VBMG6125 3.625 Stroke Callies Magnum Plus 4340 Steel LS1 Crankshaft
From the dual keyways for supercharger drivers, to a weight saving reluctor ring mount, the Callies LS1 Magnum Series Crankshafts offer installation ease and high output durability as standard features.
Each Callies LS1 Crankshaft includes a reluctor wheel welded to a unique Segmented Mount to ensure positive location even in the most severe applications. The Callies Segmented Mount, combined with generous lightening holes and CNC rod throw profiling, eliminate heavy metal for most balance applications. Machined from high alloy 4340 steel.
Lunati pioneered the development of the 4340 forged performance crankshaft for the LS1 engine configuration. Lunati supplies Lingenfelter Performance with their LS1 crankshafts for the development of the 383 Corvette, Camaro and Firebird. The crankshaft comes complete with reluctor ring installed.
