I have a 1980 I an runnig on a 1/4 mile dirt track, I recently blew the stock engine.

I would like to raise the compression, whith a early z car head or pistons and keep
fuel injection, what would be the best way to do this and from what other engines
should I get parts, I want a 11-13:1 CR.

I also have a a R200 rear-end under it, I also have a R180 fron a 81', what are the gearings of these diffs?

I was also wondering how high a lift cam I can run without hitting the pistons?

One more thing I would Like to stroke this engine, where should I look for a new crank?

Thanks alot,
I will start racing this car again in March.
