Well my crower stage 2 cams are FINALLY in! I love them. Idles lumpy, car stalls out occasionally, but it pulls like no ones business on the top end! It's kinda cool that I can just floor it from low RPMs in 1st and once it hits about 5.5k BAM tires break loose. Nifty. I got a hell of a lot of tuning to do though ... I may take her to the dyno this weekend but we'll have to see. It's running REALLY rich (I never see below ~.97 o2 voltage at WOT), it idles roughs, and it dies occasionally if I push the clutch in and let off the gas from a high RPM. But it's great. I'm FINALLY taking advantage of the ported head and the SS oversized valves. I hope to squeeze as much as I can out of it.

Nice aren't they? Congrats on getting em in, yeah the high rpm tire breaking free catches you off guard that first time.
Do you have the S-AFC in? If so drop 1k adjust down at least 7 % and idle should smooth out... most likely with the head work it will take in the 12%+ range.

So a crower stage 2 cam is approximate to a #18 crane intake, and a #10 crane exhaust? I wonder why so agressive on the intake and so mild on the exhaust? (relatively speaking) It's an unusual combination.

Well I wouldn't say its a # 10 exhaust ... between #10 & #12 and the intake is between #16 & #18. It's got a lot of lift on the intake side .389" and so so on the exhaust .357".

My thoughts on that... exhaust gas velocity, force it out quickly and in a shorter time span, you have to worry less about back pussing of the gases as well... just a thought.

I agree Mike, that's why the stock exhaust cam is less agressive thant he stock intake cam (and why the exhuast valves are smaller than the intake valves)
It's just that there is a big difference between a crane #10 and #18 so that's why I was wondering...
My new cams should be in after this weekend heh heh, gotta love competition
