Hey everyone I am looking for some info on a 500 stroker engine build. I called 440 source and asked them about a street motor set up for pump gas. They said to go with 27 dish pistons with stealth heads for a cr of 9.6 to 1. My engine builder is telling me to stick with flat top pistons and 78 cc 240 trick flows. 440 sources website says that set up will get 11.5 to 1. Im stuck on witch way to go. I have worked with my builder for years. He is a mopar drag racer for 40 plus years and has ran strokers for years. Any info would be great. Im going to call 440 source tomorrow and pick their brain..
