Does anybody wanna help a guy out on getting the most out of my hemi predator 212cc??? We run a stock appearing class on our track. (No internal modifications, stock muffler and stock breather) I am needing some tips/tricks/modifications I can do to get the most out of it. Thanks!

Thats pretty limited for sa .
Thin head gasket , clearance the rotating components , timing advance and a twisted or different cam .
Open up the air box and muffler .
