I'm at 11.89 and 8.8 compression " at altitude" I race my junk on local 93. my average cylinder pressure is 168 cam is on a 112 and my "quench" is .051 (just saying) and passing my thoughts.

Thats the best pump gas you have in Oklahoma? A state right next to Texas, the bigf oil state. Quote: I havent seen 93 in my part of OK in along time. 10 years at least. It is super lame.... Quote: Aint that a sad truth...... 93 starts at the Texas border. Best I've found is 92 at the Flying J truck stop in Tulsa.

Are you running the #s for different bore diameters as well as compressed thicknesses? Oh, in case you're not using it, the CR calculator on Diamond Pistons' web site is perfect for running all these types of calc "What if..." scenarios.

[/quote .039 fel pro .045 rol .050 fel pro .060 cometic Yes, Ive factored the different bore sizes in... Myself, I like the compression calc on Stan Weiss' website. I'll check out the diamond calc. 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72. Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.
