Quote: The CH of the KB400 is 1.908 , the CH of the 2315 is 1.920.
What I meant by inefficient is the dome impedes flame travel across the chamber , a flat top doesn't . I am building a 383 based stroker with 12.5 compression and the only way to do it was either cut the bleep out of the heads or use a small dome , I chose the dome , should have cut the heads
What is the CH of a stock 383 piston? I can't remember but I thought it was less than the KB400 1.908.
I understand what you mean by the dome "getting in the way"....but how does that affect your car? Decreased performance? Gas Mileage? I was looking at getting the dome to help with CR since everyone was saying 9.5:1 wasn't enough for that cam. The dome would put it about 10:1.
