Thanks for the advice man.i didn't mean to sound like I just wanted a cool sound..I really just want the best cam for the items I described earlier.if I can get a cam with a Lopey l.s.a. then that's just a cherry on top.as for a roller setup.i bought an ls1 with the intentions on building it.but block turned out to be trash.so I'm out the money spent on that stupid ls1 venture.that I had no business trying.so now I'm short on cash.but, this motor only needs to get me by for a year or so.i currently have a big block I'm trying to build that I hope will be done in a year or so.
But anyways. Here are some of the cams tjat have been suggested.in case you or any one else could suggest one

Colt cams flat tappet
216 intake
225 exhaust
At 50 112 l.s.a.

Crane cam 100132
222
222 at 50

Crowder cam
00223
214 intake
224 exhaust at 50
110 l.s.a.

I have no idea which of these cams to go with.all 3 manufactures say theirs are the best.but the guy from Colt seemed to think that the pet cams listed would not supply enough vacuum. And thati don't have enough stall to run them..

Any help is greatly appreciated
