What would be the most compression a guy could run on E85 with out haveing to make compromises like retarding the timing? this would be a 4000 pound street car with 3.54 or 3.73 gears with a Passon 20% overdrive gear in the 4 speed. Specs on the motor:
484 Hemi 4.310 bore x 4.15 stroke ported iron heads hydraulic roller cam 226/230 at 542 lift 112 lobe centers Inline street Hemi intake with AFBs exhaust manifolds and 2.5" exhaust
Thanks, Joel

Thanks Dave. I think I have most of the parts on hand to assemble a 12.8 to 1 motor. I didn't know if I should use a thicker head gasket to drop the squeeze down a bit. Sounds like I should put it together at 12.8.

I learned a lot from the info at www.E85forum.com. Lots of good stuff there to help make the right decissions.
4 speed street legal. Best time 10.99 @ 124 mph on 93 octane pump gas @ 3926# total weight
