Questions about 383 Stroker
Well in particular, the stroker part.
Whats the difference between a 383 and a 383 Stroker, or better yet any engine that is a stroker. What makes it a stroker and how is that better then not being a stroker?
Thanks in advance for the somewhat noob question.

Just found this on the google search.
As with any “stroker” engine, the 383 stroker uses an altered crankshaft to increase the stroke of the pistons. This increased stroke allows you to get more air and fuel into the cylinders, thus increasing displacement without changing engine blocks. The increased fuel and air means more horsepower and torque!
The Chevy 383 Stroker is an 8 cylinder engine that uses the popular production Chevrolet 350 block and a slightly altered Chevrolet 400 crank. A stock 350 has a piston stroke length of 3.48 inches. The 400 crank changes the 383 to a total stroke of 3.75 inches. This produces a total displacement of 383 cubic inches (thus the name 383). This displacement means that a Chevy 383 Stroker is capable of drawing in a total of 383 cubic inches of air/fuel mixture into it’s cylinder chambers during one cycle of the 8 pistons.

I think the term stroker is kind of old school, when they did have to use a cut down 400 crank. Now you can buy any crank you want 3.62,3.75,3.875,4.00,4.125 any of these cranks will fit in a 350 block. some easily some not so easy!!
