Fits On/Installation Notes:
Its extra displacement and unique parts are designed to build a wide,
flat torque curve that hits the 400 lb.-ft. mark by 2,500 rpm and doesnt
dip below it through the 4,000 rpm peak (435 lb.-ft.). It also makes 340
horsepower. Thats power and torque you simply wont get with a stock-
type rebuild.
The HT383 features a brand-new engine block with four-bolt mains
an upgrade for most production engines that came with two-bolt
mains along with a forged steel crankshaft and a smooth hydraulic
roller camshaft. Its 9.1:1 compression ratio allows it to run on regular
unleaded gasoline, too.
