havent really decided the cam im going with but want to be sure that with whatever i choose it will clear the pistons using the prc 237cc head. (2.100/1.6 intake valve)

i was thinking of a cam around the size of the tsp tsunami. .648/.609. i was thinking of ordering the -3 cc valve reliefed wiseco pistons or would i have to go with a -8cc?

thanks in advance. looking to order in the next day or two

-8 or -10 and you will be golden..
it will also keep your compression up which will help with power and driveability with a bigger cam

thanks, i figured at the very least i would need to go with a -8 just to be safe.

I'd go -3cc with those heads. That way you will not need to mill as much to get your compression back up where you want it for an NA or nitrous build! With the -3cc piston, GM MLS gaskets, and the standard 68cc you will net right at 11.3:1 static compression!

Matt thanks. i talked with john on the phone today and thats what i ordered. told him which heads i was planning to order from you in the future, and possible cam size. and he recommended i stick with the -3cc. but unfortunately they are back ordered til the end of the month its ok though. no worries.

i was talking with the machine shop today. he was talking about possibly decking the block. will i run into any issues doing this with the prc 237cc head/-3cc piston?

Either one should net you the same valve clearance but the -8cc has an additional dish. I went with -8cc pistons because it's easier to gain compression than try to add it, generally speaking... See signature for -8cc piston.

It shouldn't be an issue. Just have the machine shop verify where any decking puts the piston (out of the hole) and that you pick your gasket thickness accordingly!
