[QUOTE="ModularSpeed, post: 11659471, member: 56332"] California, 91 Octane.....yuck. In your particular situation, mid 8's may be the better route....as far as simple is concerned. If it were me, I would run well into the 9's. Probably 9.6:1 to be exact. I am a firm believer in less boost, more compression, and proper cams that are also timed appropriately. A 3.7 bore combo with the right headwork and proper cams would be able to perform pretty well on a boosted combo with 91 octane and 9+ C/R. ALL boost makes more power with more compression. As long as the IAT's are in check, you can get by with a decent amount of compression on pump gas. On a 99+ DOHC V-8....I can say for 100% certainty that a turbo, PD, and centri combo will make the same power at 9.5:1 on 18 psi as the same exact combo with 11.0:1 and 15 psi. [/QUOTE]
