I currently have a 427 n/a motor (4.125 bore) w/ TFS 235 heads that were milled to have 62cc chambers. Is it possible to get pistons that would result in having a 9.5:1 compression. Max horsepower would be in the 1,000-1,100 range. Or would I need to purchase new heads? Thanks

I don't have a CR calculator here, but I'm sure you could order a piston with enough dish to it to get the CR you're looking for.

9:5 or so is what my scr is. 427 with a 64cc head. dish volume is between-28 to -32 cc.

Ok, thanks. I really didn't think it was possible.
