Back in the 90's, had a friend that bored a 383 70 over and put a set of standard bore 440 pistons from a 76 new Yorker in it. The low comp. 440 pistons were almost zero deck. It ran real good for a cheap build. The only bad thing is no valve reliefs. He ran the 484 purple shaft in it with small valves. Just an idea. I built a 440 along those years in 2008 and checked the deck height before I pulled the pistons. They were .160 in the hole. Crazy low comp. Its a wander the last years of the 440 made any power.
