old rings

well here is the story i got from him. the 318 is really a 5.2 in a 67 valiant 4 door!(can't wait to see it!!!) He is going to drag week with hot rod magazine. he doesn't have time to brake in a motor. so he wants to pop the pistons gap them reinstall and go. he wants to run low boost. turns out he has a pair of t4 turbos and will run them at 8PSI for drag week then rebuild it afterwards. I think if he can keep the boost low it might work. but he is doing it so we will see!!!!
