CNC,That would be great but I hate to put you through all of that. It would be a fantastic reference to have stashed on this site in the Tech Tips or where ever. My needs are fairly simple. I want to take Bill Fisher's idea of destroking a 270 a step farther. I want to bore a 302 to 4 1/8 and use a 228-248 crank. It would have 305.7 ci and should wind a bit higher because of the shorter stroke 3/16. I don't want to deck the block to get the piston up in the hole incase it doesn't work. I don't want to wreck a block. So I'll need a 3/32 taller piston if I stick with GMC rods. Are these rods forged? If they are why couldn't they be reforged, heated and stretched a bit?
Ron, I'll be looking forward to seeing that. Yes the length of the piston is a problem and my plan makes it longer!
