I’m working on my 428 with a 455 crank and 96 head d port head engine. I’d like to achieve as close to 9.5 to 1 comp ratio as I can- given my understanding CA 91 will work without detonation. I plan on buying new pistons for the engine and custom is an option. Does anyone have experience with custom pistons that have a small dome in the spark plug side of the combustion chamber only? As in the small dome just enough to get the proper CC from the spark plug going away from the valves. Then I start to wonder if my efforts to unshroud the valves in the combustion chamber would be for negated with the dome? What do you think? I’m just a lineman not an engineer.
