I just purchased a eagle crank that was a sock 460 stroke that was offset ground. The stroke is now 4.135 and rod journal is for Chevy 2.20. The question I have is what rod and pistons do I use? I have search the internet for 4.135 stroke 460 cranks but all I find is 4.140. I believe I should use the BBC Chevy 6.8 rods and then a piston from possible keith black. Any help would be greatly appreciated.
