I just did some math and you are looking at .27/.36 difference in compression from the 82/83 to the 86, I used a .030 over 440 for the calculations. In a mild street motor that's probably not that big a deal.





That's what I was thinking. Based on the variability of deck heights across a typical non-square Mopar block, I would think this level of variability would be pretty common and not much of an issue, but my new machinist seems to think it will be a problem.

I guess that before I do anything else, I'll have to bust out the buret again and doublecheck my numbers.
