Nope. No way no how. Not without a camshaft that's way too large for the engine. a true blueprinted 9.5:1 with a matching camshaft even requires premium fuel and still may detonate in really hot weather. An honest to goodness 10.1 engine is a high compression engine. With alloy heads, no problem on premium fuel....even perhaps to 11.1, but no way with iron heads. It's misinformation to think that. If someone says they have done it, either one of three things is true. Either they are running a camshaft with gobs of duration to bleed off cylinder pressure, or they did not blueprint their engine. Or both. It would take a camshaft of about 250 degrees
[email protected]" and 108 lobe centers or less to bleed off enough cylinder pressure to run 10.1 on pump gas and that's way too much camshaft for that compression level. Sure, it can be done, but you will NEVER, EVER achieve the power level that you could at a lower static compression with a properly matched camshaft. I'd rather have a good blueprinted 8.5:1 engine with a mild cam any day on the street in comparison. I'd smoke that overcammed 10.1's butt, too. Done it many times.
