compression ratio on pump gas
Thats why I posted mine will be around 8.7-8.9 with magnum heads. I think I talked to dgc333 about his dynamic and I think it was 8.6-8.7. But with everything I have read all over the internet says 8.8-8.9 is 93, but idk. Im just going off what my engine guy aka Brian said! And he seems to be making stuff work correctly, so I believe him, but if it doesnt work, then I will mix gas or just lower timing. Not that big of a problem for me, but for others it might be!
