383 Chevy Long Block

$5,899

The 470 HP version of our 383 Chevy Small Block Stroker is a step further in the direction of performance engines. It features a torque curve that is moved slightly higher in the RPM range resulting in a rougher idle and less low range torque than the 420 HP version. If you like to turn the wick up a bit on your street car, this may be the crate engine for you!
