Thanks for your input Im ordering custom pistons for my project and will of course need some guidance.
Machine shop said my block needs decking so other than that my components are cut and dry
Im running stock stroke with factory steel crank and Scat 6.123 H beam rods and would like to have around 11.5.1 or just under 12.1 compression I found a nice piston with the specs close to what I want but of course its offered for the 4.0 stroke engine.
