Do you want to take your Hot-rod or 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.
We have over 100 years of combined experience with handling GM parts and Accessories. GM parts and Accessories are back by a industry leading warranty. They are all made to the Genuine GM specs that family's have been driving their family around in for many many years. We do not sell the much less stable aftermarket parts and only ship A+ grade new in box GM parts to your door.
