Chevy ZZ4 Fastburn Engine 430HP - $5600 (West Chester
Used, About 15,000 Miles on the engine
The Engine has been upgraged to a ZZ430 Clone. I installed the lt4 Gm Hot Cam kit
The duration at lash point in degrees (intake/exhaust) is 279/287; duration at .050" tappet lift (intake/exhaust) is 218/228; and maximum lift with 1.6 rocker ratio (intake/exhaust) is 525/525. Which were installed gunine Gm Roller rockers Valve lash is zero/zero and lobe centerline is 112 degrees.
Right from Chevrolet Performance comes the new Fast Burn 385 which uses the proven ZZ4 350 cubic inch short block and ads to it the fast burn aluminum cylinder heads for approximately 9.61:1 compression with 385 hp at 5,600 rpm and 385 ft./lbs. of torque at 4,000 rpm. Recommended max rpm is 5,800. Installed into these 4-bolt main blocks are internally balanced forged steel crankshafts, 5.7 in. powdered metal connecting rods and hypereutectic flat top pistons with offset pins, which are the same pistons, used in the Corvette LT1 engines. Camshafts are hydraulic roller and rated at .474 in. intake lift, .510 in. exhaust lift with duration at .050 in. being 208 for intake and 221 for exhaust. Stamped steel self aligning rocker arms with 1.5:1 ratios are installed on Chevrolet Performance aluminum Fast Burn Heads with 62cc combustion chambers, 210cc intake runner volume "Fast Burn" combustion chambers with 2.00 in. lightweight hollow stem intake valves and 1.55 in. sodium filled exhaust valves. LT4 Corvette valve springs and light weight retainers are used. These heads have "D" shaped exhaust ports and have dual bolt pattern intake manifold and valve cover configurations. Intake manifolds are aluminum dual plane square bore only carburetor flanges similar to Edelbrock Performer RPM Vortec manifolds. They have provisions for an externally plumbed hot water passage underneath the carburetor for improved cold weather drive ability. GM HEI large cap distributors with internal ignition coils are used. Additional parts supplied with this kit are 8 in. harmonic balancers (degreed), 12 3/4 in. automatic flexplates, and 4-quart oil pan with windage trays. Painted valve covers with oil cap and grommets provisions for PCV and breathers. Composite (plastic) front timing cover and spark plugs to complete the install.
The engine is still in the car and can be removed as soon as 50% of the payment is made. You are welcome to drive it to test out the engine. Its currently in a 1984 Pontiac Trans Am
