Hi ron just want to say you can go wrong with dewayne. he also set me up with a set of indy ez heads and a comp solid roller. so far with no tuning my pump gas 440 in my 73 dart street/striphas run 10.68 at 125 and my car should weigh around 3400-3500 pounds with me in it. so i see no reasion your car wont run 10 or better. best of luck on your new engine.
