Chevrolet Performance 19435448 - HT383 Crate Engine - 323HP

Is it time to take your Pre-1980 GM truck to the next level. We have a solution with the big-torque HT383 crate engine. The displacement gain and unique parts were chosen to guarantee a wide, flat torque curve that will supply at least 400 lb.ft between 2,500 and 4,000 RPM. The engine starts with a brand-new block with four-bolt main caps – a strength-enhancing feature most production truck blocks don’t have. The crate engine includes: a forged steel crankshaft, heavy duty PM steel rods, hypereutectic aluminum pistons, smooth hydraulic roller camshaft, iron Vortec heads, and aluminum intake manifold. The 9.1:1 compression ratio is perfect for regular gasoline at all altitudes and engine loads. Ready for you to swap over the accessories from the tired SBC. It is also backed with a 24-month/50,000 mile limited warranty.

Fuel Pump and Flex Plate no longer included!
