You're a lot of help

Let your "engine guy" help you make the right decision for your package. Things like relief size, distance from piston top to top ring, etc. all come into play when spec'ing a setup. Don't outsmart yourself piece mealing the cheapest of the best from various online sites....

 

I like the Detroit Pistons.
