Re: 383 question.

there are many ways to build a 383. You'll need to find one to suit your budget.

using a 400 crank with 400 rods

using a 400 crank with 5.7 rods

using a 400 crank with 6.0 rods

using an aftermarket crank with any of the above rods

buying an entire 383 rotating kit with all the parts ready to go, balanced, etc is the easiest.

there are literally dozens of how tows, part numbers, pictures etc in this forum alone--even more on the internet.

pick a power level you want to achieve, driving style you want, and go from there.

Re: 383 question.

The diameter of the damper isn't important. What's important is whether the stroker crank is internally or externally balanced. That information comes with whatever crank you get - and your machine shop better know which they are building.
