Just got the intercooler installed. Turned the boost back up to 15psi and tuned the carb to it so it stays nice and rich. Runs like a top but is ruining the block. The rings are taking a beating and blowby is becoming a lot more apparent. The oil still looks pretty clean though so I don't think I've broken anything. I'm saving up to finish rebuilding that other block and I found a set of apparently forged pistons for my 250. They're from the later era with the integral head and it has "0.015 higher compression distance but I don't know if that would be enough for it to hit the head when it's all bolted on. It seems like it wouldn't be a problem with that thickish fel-pro gasket with the metal rings built in and it would just raise the compression some.
