I know all about the issues with using these pistons vs the originals.
I built a 430 using these Egge replacements,since I wasn't able to find an orignal set at that time. I did have the orignal cam reground to a 429 cobrajet profile,which does have different duration,and would increase compression ratio some. I havent' installed engine or fired it yet. Just having second thoughts before I do. Appreciate any info. Tom
