Guys, I think whst 2300 is refering to is using the earlier rotating assembly in his 01 block. Does this raise the compression ratio? I believe he said that It will make it about 10, 1 to 1, If so, is this safe to run on pump gas? And I have a question. What is the highest compression ratio that can be safely used wth these engines on pump gas? Opinions please. Thanks.

I would recommend 91 to 93 octane on it. Though i still run 87 on mine and have been for quite a time. Yes compression is higher (10.52:1 cliffy will correct me im sure of it lol) however i run 87 and every time i run 93 doesnt last long as 87. However its just me i would suggest atleast 89 since the compression bumped up due to the pi swap.

The previous owner of mine dropped an entire PI motor into it and it runs like stock. If you are talking about just doing the PI heads/cams/intake onto a NPI block you'll bump compression up to around 10.5:1 and may or may not need a higher octane gas. I put 93 in mine all the time just to be safe although I doubt I need it. The PI is designed to run on 87. However, premium is like what $2 extra per tank? At least around here it is only about 20 cents more per gallon times usually a 10 gallon fillup from a little below 1/4 tank. This isn't enough of a difference to make any difference at all to me but I suppose if the price difference was more it might.

I solved my problem I'm gonna grind the hump above the intake valve flush with the cc chamber to give the cc chamber more volume
