I have a block in storage that I had sonic checked a few years ago. 454 most of the numbers came back around .160 some as high as .220 but two are .139 these are one on each bank at about the two o'clock position on cylinder 3 and cylinder 6. I plan to turbo this block. From what I can find these are good numbers. Do you agree? Do you think I should try to move these cylinders .005 away from the thin side? I have pistons to either go .030 over with a 4" stroke and .060 with a 4.250" stroke.
A penny for your thoughts.
