alright, i'm trying to figure out what the maximum cam duration and lift i can run on my current setup without valves hitting pistons. is there some sort of calculator i can use online?

my current setup: type r block w/ je 81.5mm 11.5:1 pistons, eagle rods, stock crank, and a stock GSR head. I want to get cams, but i'm not sure how big i can go with the gsr head.

any advice is appreciated.

 

what kind of cams are u running right now. ITR cams are good enough or i have heard skunk2 stage 2 cams are good too.

 

just stock gsr cams. thats why i wanted to upgrade... i wanted something pretty aggressive, so i wanted to start off with how big i COULD go.
