big bore

[4TraxRider]

I am going to get a 440 kit for christmas, but was wondering if i can get one that has a compression ratio of at least 12 5 1. I have access to 111 octane race gas. Anybody got any suggestions or opinions on whats best. Tnx.

you can get a wiesco 11.1 for 219$

You should be able to get a 13-1 JE piston with no problem.
