Most of the off the shelf pistons I have been looking at are diamond or icon. I may also get a custom set of Steve Morris/ diamond pistons. The CH of the piston will not be shorter than 1.300 because I don't want the ring pack getting into the pin area and also I want the stability.
I understand the adage of "no replacement for displacement" but this engine has a multiplier on it. I can create the defiance of 40cubes fairly easily. My goal is to find the more stable platform. I have read that the higher RR will give the piston more time at TDC and narrow the window for the tune but stabilize the piston and reduce the side loading of the cylinder wall. While the lower RR will widen the tune window and promote better cylinder fill on a boosted engine. This however comes at the cost of piston speed and side loading of the cylinder walls. This is my dilemma unless someone can tell me the RR is so close that it will not matter (my green light to go big) or the side load of the 512 combo mixed with boost will cause issues (my green light to go small).
let me add this: Stock block (I know it will be a grenade but it will be as bullet proof as I can make it) and I plan to make about 1200HP at the crank.
