how high of dynamic compression can you run on pump fuel? Just wondering how much dynamic compression can be run on pump gas. Most of the gas stations around where I live are 91-92 octane and I am wondering if I will be okay with that. Here are my engine specs.
Bore 4.03
Stroke 3.75
Rod Length 6.00
Piston volume -18 (SRP said -16 but machine shop checked and -18)
Head Gasket .038"
Deck Height -.010
Cylinder head volume 53cc
Intake closed @ .006" 66 ABDC
Thanks.

Your SCR is 10.628
DCR is 8.413
You'll have no problem with Super unleaded 91-93 octane. You have a very small cam in there, with that 66* ABDC. Mine is 79* ABDC for my stroker...
Oh yeah! I'm assuming this is for an LT1 engine, otherwise I would drop that DCR with a bigger cam or retarding 4*
