Which Cams?

Look at the VT's

Here are my options. BTW heads will be ported with new valve springs...

All are $599.95

VT STAGE 1 N/A CAMS
Work with stock valve springs. RPM Range 2500-5500. Noticeable idle. Tune suggested. Gains of 25-30rwhp. 540/550 lift, 224/226 .050" duration, 110 LSA

VT STAGE 2 N/A CAMS
Stage 2 cams are the perfect choice for ported heads and all out N/A street/strip performance. MUST BE USED WITH AFTERMARKET VALVESPRINGS. Aggressive idle. 3000-6500 prm. Gains of 30-35rwhp are common. Like 3.73 gear or better and 2800+ stall in auto's. MUST BE TUNED AFTER INSTALL. .560/.575 lift, 225/235 .050" duration, 108 LSA

VT STAGE 2 SC CAMS
These cams gained 87hp and 49ft/lb over stock PI cams on UNPORTED cylinder heads. Suitable for daily driven cars. Noticable idle. Will support up to 600rwhp. VALVESPRING UPGRADE REQUIRED! .530/.570 lift, 220/230 .050" duration, 112 LSA +4*

VT STAGE 3 SC CAMS

Aggressive street/strip profile. Aggressive idle. Supports 600+ RWHP. Valvespring upgrade REQUIRED. .545/.545 lift, 236/242 .050 duration, 115 LSA.

I decided against n2o since I want the power all the time. :D Only driven in the summer btw :)

You are going to wait a long time for VT N/A cams. I would look for a cam grind that is not exhaust biased. Crower and Comp has cam grinds that fit this bill.

a somewhat mild cam will do you just fine with the blower. you really have to consider not running a really aggressive cam since our brakes are vacuum assisted...hint hint.

These cam threads give me headaches thinking about all the time I spent over-analyzing comp vs crower vs crane vs VT vs custom from one of the above. The mild comps (262) have the widest LSA, the VT's have the tightest. The crower/crane grinds are in between. There isn't alot of difference, frankly. BUT do a Search and you'll see that the people on this board who KNOW what they are talking about agree that even if you could get the VT's, they aren't a good choice in an auto-equipped bird because of that tight LSA - makes HP on top, but trades it off down low where it's needed on the street.

Like I said in the other thread, you DON'T want VT NA cams because the low LSA will really hurt your vacuum. Plus if your going SC next year, you'd have to do another cam swap then.

Go with the Comp 270AH (no advance) or the crower 62802-2.
