The problem I've had is very few of the ads for stroker kits give piston part numbers, or details like valve reliefs.
I called Summit. He said none of their dish pistons for SCAT kits have valve reliefs. Then he said all their SCAT kits are for LA engines, not recommended for Magnums. Wrong rep to talk to I guess.
Assuming my block will be shaved about .010 with 61 cc chambers, .040 gasket, we have calculated that I'll need something in the 23 - 27 cc piston to stay in the 9.5 to 10 CR.
Planning hypereutectic, unless forged are within $100 or so.
I'll have more conversation with the machine shop before an order is placed. I'm just trying to know what's available in advance.
