Well I have a c-4 with a 3.55 gear. The stall is a 3400 rpm.

I was wondering what would be required to make it run on pump gas and And be a lillte more street friendly.

I was actually thinking about selling my 347 to build a low compression ratio 377 stroker and put a turbo on it.

I am woudering if I should trade with him and change his combo a little or leave it the way it is and just run it at the track or just sell what I have and built the combo that I want or stay with the motor I have.

I could probably talk him in to letting me keep my heads and him keeping his and that would help the compression ratio a little. He said he had the heads shaves a lot to raise the compression.

He said he thinks with my 58 cc heads the compression ratio would be around 11 to 1. I think he said his heads were like 43 cc or something like that. Would that change the compression ratio that much?
