Which cam for Ported LT1 heads?? I am looking for the grinds you guys are running with Stage II or fully ported LT1 castings along with Dyno numbers and/or time slips if you have any.
I am currently running a fully ported CNC'd set with a hotcam and would like to make the most out of the heads by going to a bigger cam.
I did a search on this subject and found some cams but not any specs. Please include specs with your cam along with likes and dislikes.

I want to know what everyone is running with their ported heads with possibly dyno numbers backing it up. Specs of the cam grind is what I am looking for.

If your "Stage II" heads, displacement, compression, exhaust, trans, gears, etc. aren't the same as someone elses's, just looking at their cam specs won't really help much. Perhaps the faster guys aren't going to reveal cam specs anyway.

Look man, he asked a simple question. He wanted some dyno numbers from some particular cam grinds using fully ported heads FOR REFERENCE PURPOSES.

here ya go.. my first setup was ported stock heads (valvejob, shaved, and pocket ported) with a cc305.. made 352hp 340 tq.. second setup is going to be set of "stage 2" ported heads with a custom grind cam.. its kinda small too.. .510 intake lift/ dur.@.050 230 degrees .520 exhaust lift / dur. @.050 236 degrees.. im still not sure if im using that custom cam or simply going with a gm847.. might go gm847 for higher numbers, but with my boltons both cams should give me around 400 hp

i made the numbers in sig with my setup which the heads where just lightly ported, now im waiting on some stage 2 heads which will hopfully put me in the 410ish area. and the specs on the cc306 are 230/244 .510/.540 and then the 1.6 rrs bumped up the lift a little.

How about this: better flowing heads require less cam than lesser flowing heads to get the same power. Not all "Stage II" of "fully ported" heads flow the same air or with the same quality. With a cam matched to the entire combination of engine and vehicle, you'll see better area under the curve and peak numbers. That doesn't mean the cam needs to be "bigger" as Docspeed suggests, it just has to be better suited to the engine. If you don't have all the relevant data, you are just picking a cam by bra size.
