Re: supercharged cams? I really like that cam also...especially with 1.8 Crane RR.
If you'd like to go bigger in duration, something like a 224/228 might work well for stock displacement. That should keep the power under 7000rpm. Too much more duration and you'll be shifting in solid roller territory.
I'd keep it around a 114LSA (any tighter and you might get blow through and lose boost).
As for lift, you want to set your lift according to how your heads flow. No use running a .600 lift if you're getting port stall at .580 (just an example, for I have no idea what your heads flow).
BTW, was that time in your sig with stock H/C and just the vortech?

Re: supercharged cams? fasst those times were with an old set of jpr heads, and with a 216-220 cam on a 114. i had major lean isues and popped the motor about 3 runs later. live and learn. my fuel pressure was dropping about 20 lbs. stupid me never put the gauge on right away i was waiting for the fittings and got impatiant. the heads i have now are 6.0's and really flow awesome. im thinking of going a bit bigger on a cam not sure what size yet, but i will almost definatly go to a 116 to try to get back some of the boost i lost. I lost almost 4lbs of boost when i put that cam in. so i switched pulleys. My car trapped 128 mph when i put a maft on it to fatten it up, but it was still too lean. has anyone tried any real big cams favoring the exhaustside?
