Alright well I've gotten all my parts together for my build-up, but I'm still trying to decide on just how to rebuild my 22R. I want to run propane for sure. My original thoughts were to run a 22R with LC Engineering 12:1 94mm forged pistons with their master rebuild kit and 20R head with 22R intake valves(i was told they're larger). I'm still not sure what to get for a cam, I would appreciate suggestions. I was hoping someone could give me some suggestions on an engine build. Thanks!
