LT1 / LT4 engine fresh!

Now for the engine, it is a 1996 5.7 liter small block, LT1 out of a camaro Z28. I had this engine rebuilt by (race engine builder) Brad Sain Automotive Machine shop. All the bearings bolts etc was replaced with premium parts. Some of the goodies are as follows: LT4 hot cam kit, this kit comes with the cam, roller lifters, 1.6 roller rockers, & valve springs. GM part # 12480002. Kit description: This off-highway camshaft kit has the major valve train component to convert production LT1 Engine for showroom stock racing, or hop up your small block Chevrolet V8 that was originally equipped with a roller tappet camshaft. The 1.6 roller rockers, light weight valve spring caps, special designed valve springs and hot camshaft offers a significant gain in horsepower at a reasonable price. This kit includes the following items: one camshaft P/N 24502586, 16 roller rocket arms kit P/N 12370839, 16 valve springs P/N 12551483, 16 valve caps P/N 10212808, 16 valve keys P/N 24503856, 16 valve spring shims P/N 10212809. Does not include roller tappets. See valve lifter section for the lifter kit. Engine also includes the the heavy duty LT4 timing chain GM PN # 12370835. Description of timing chain as follows: LT4 Gen II Engine extreme duty timing chain kit. Single roller design, with billet steel gears. Much stronger than the OEM morse link style chain. Includes chain, cam gear, crank gear, water pump drive gear. Water pump drive gear needs to be pressed onto original shaft. The chain kit will only work on 1994-1997 gen II engines that have pin drive opti-spark. In order to use this kit on 1992-1993 engines with spline drive optispark, engine must be updated with a 1994-1997 optispark unit and a 1995 timing cover. I also upgraded the oil pump to the LT4 high pressure oil pump, GM PN# 12555884 : Production high-pressure Z-28/LT-1 oil pump with 1.20" gears. Will produce 60-70 psi oil pressure. The intake manifold is another GM performance part, it is a carbureted intake for the LT1/LT4 engine. This intake lets you run a standard SBC distributor. GM PN# 24502592 ual plane GM Performance Parts' Carbureted LT1 intake manifolds make it possible to take advantage of the advancements found in Generation 2 Chevy engines. They allow you to install a carburetor on your LT1 engine without the hassle of running a computer or emission controls. They accept both Holley and Quadrajet carburetors, and feature longer runners that increase engine torque by up to 30 ft.-lbs. without sacrificing top-end power. The aluminum heads were milled.020" , & rebuilt with premium parts



make me a reasonable offer!
