Sorry to resurrect an old thread, but I'm about to start ordering parts for this thing, and I've got some more questions. The static compression ratio that I'm coming up with for my planned combo is coming out to 10.87:1. Is this too high for pump gas? (91/93 octane). I know that until I cc everything and blueprint the engine, I won't have an exact CR number, but I'm just trying to get a good idea for now. I know that with the right cam I can get the DCR numbers to the "right" levels for pump gas, but it seems like everyone on some of the other engine forums has a different opinion on whether or not DCR is something is be concerned with or not. Any help would be appreciated and for anyone who wants to double check my calculations, I've listed the combo below. Also, JamesonRacing, you said your street Fairlane is at 11:1, just curious as to what fuel you're running.
The tentative parts list:
.030 over 390 block milled for zero deck
Survival stroker kit, 4.25 in crank, 6.7in rods, 1.330 in compression thickness flat top pistons with 6cc valve reliefs
.041 in compressed thickness head gasket 4.400 in bore
Survival heads Nominal 76cc chamber
