building a 427
What cid would I be at with that crank? Also, what type of crank shaft is it that is used in a 360 block to make it a 390?

If you use a 428 crank with a 390 bore you have a 410 (mercury 66-67) but you have to either have a 390 piston shortened or use a early 70's 390 low compression truck piston. To make a 360 into a 390 you have to have 390 crank and rods and sometimes you can use your 360 piston, depends on pin height and your desired compression. either way you would probably have to change rods crank and pistons. I will have a good 428 crank for sale when I order my stroker kit I also have lots of 390 cranks and lots of rods. Good luck

Scat has some stroker cranks and you could use one of those to get the cubes but they couldn't give me any details at all about the installation or where to find pistons, piston rod combos ect.
