Stock 460 dish pistons D1 block D3 heads. How much power diff. would I notice by swapping to a set of ported DOVES, 2.245-1.725 cut .30 Approx 72cc chambers?

The d0ve heads are around a 75-77cc chamber vs your D3 heads with their 95-97cc chambers, youll bump your comp ratio up to around 10:1 and definately feel a difference. Exact power gains, on the other hand, are anyones guess. Just be sure to run at least 91 with the D0VEs

Thanks, that was a question I wanted to ask also. How much of a detonation problem will I have with 93
