Thinking of buying a 4.25" crank and 7.100" rods from them for a 512 stroker build. Planning on using the stock bolt pattern for the flexplate although they mentioned offered an 8 bolt pattern.

A couple of other questions that I have are:

As long as I pick a piston with the proper CH, should it work well with the longer stroke crank and 7.100" rods? I think the piston should be somewhere around 1.485" to get close to zero deck. Pistons I'm looking into are Diamond or CP, although I did find these that give me the CH I'm looking for:

Is the B&M flexplate a good piece to use for a 512 build? I can't remember the part number but it was for an internally balanced engine and it was a circular flexplate instead of the "X" shaped factory flexplate.

Thanks

If you are going to use the Crower crank and rods. I would use the Diamond or CP pistons. I believe they would be a little lighter and of higher quality. JMO
