Every Pontiac I own is less than 9:1 and they run great. No cooling issues and they have fantastic torque. They run on 87 octane and NEVER ping. Idle great and no gas smell from the exhaust.
R.H.R.E, just dynoed a Poncho the other day. With no tuning (Ran out of time) he made almost 400 HP, I think like 375. With 8.7? SCR
IMHO, I would rather have almost 400 HP on 87 with no issues than 420 hp and some issues. That's just my .02$ Just keeping the conversation going....
