I'm about to pull the cams out of my P5 and send them to Crower for a build up and agressive regrind, but if anyone has swapped out their OEM cams for the J-spec and still has the OEMs laying around, I'll buy them and send those instead. That'd cut down on the time I'd be without the car. How's $40 a piece sound. I can even send my OEMs back to you when I'm done.
I'd also will need to give Crower the profile specs to grind to. Does anybody have an idea of how much lift I can get on the stock valve springs without float or bind? How about duration and over lap? I'm thinking about 233 intake/225 exhaust, and adjusting in about 6 degrees lap for starters. The head will be cc'd and decked for 10.5:1, and lightly ported, maybe extrude honed too. Any ideas?
