can you run 11:1 compression on street with pump gas??
I am curious if you can run an 11:1 engine with cast iron heads on it on the street with 93 octane gas. If a cam grinder custom grinds a cam will it be able to or is it just to much compression?
engine is a 552 ci, fully ported D3 heads, headers, 1150 dommy, new TFS intake, zero decked, flattop pistons, fox mustang car, 4.11 gears, 3,000 stall, don't have cam yet.

With a big enough camshaft, keeping the engine temperature down and well controlled ignition timing ... YES.

Yep, cam be done with the right cam and good tuning skills.

I'm using flat top diamond pistons and P51's with around 12:1 compression.
I use a 91 octane 10% ethamol blend of gas we have here in Alberta from Huskey with no issues.
