cc306 vs hotcam
hello
How much more power, and how much will the power curve change when going from a hot cam to a cc 306 cam on this setup?
Miniram
afr 195 heads
hooker headers
no egr no airpump
6spd
And will it pass "sniffer test" ?
thanks

Re: cc306 vs hotcam (devilfish)
Top end will be stronger, would need some rear gear, doubtful that it'll pass a sniffer

Re: cc306 vs hotcam (devilfish)
he sniffer test is tough to pass with a 306 cam. Probably will not have much power until 3K rpm, then pull to 6500. Lot of Camaro guys use them in their 350CID LT1's, but I feel it need more cubes to be a good cam. Not worth swapping to IMO. Yes you will get more peak power, but it may actually run slower in the 1/4.

Re: cc306 vs hotcam (devilfish)
Well a little input to the desktop dyno and here's the differences between the LT4-HotCam and CC-306. I used some general specs for the engine such as 11:1 CR and I also used the AFR 195 heads you were talking about. If you want me to change some specs let me know.
LT4 HotCam:
CC306:

Re: cc306 vs hotcam (devilfish)
I think that cam is a little to big, I would go with something like 220 intake and 230 exhaust around 0.540 lift on a 112 that cam would be good from 1800 to 6000 rpm.

Re: cc306 vs hotcam (devilfish)
I think thise .510/.540 lift numbers for the CC306 is for 1.5 rockers, the 306 is a pretty big cam.
With 1.6rrs it would be .544/.576. I was looking at the 306 when I was doing heads/cam on mine. I ended up going with a Crane cam that was smaller (.542/.563 222/230 dur) mainly because I didn't want to have any trouble getting through emissions.

Re: cc306 vs hotcam (devilfish)
IMHO, I too think the CC306 is too big for this application. I had the opportunity to listen to a 383 stroker with the 306 and I did not like the way it sounded at all (way too lumpy). The guy that had the 383 ended up pulling that cam because he didn't like it either.

Re: cc306 vs hotcam (cprgmr)
Check out the comp cams site, their catalogue, look for Chevy LT1. There's an LT1 specific cam there that's a few degrees smaller than the 306 - I'm looking at that myself with LT1 190 AFRs. The 195 heads are geared more toward the upper rpm ranges and the 190's flow as good or better up to the higher mid ranges, check them out on the AFR website. Also check out the dyno articles on that site, and on LPE (Lingenfelter Perf Engineering) - lots of VERY stout 383's use the 190 heads and either the 306 or 1 - 2 steps smaller, drops torque peak down to about 4k but puts out usually 425+ torque at 2500, peaks near 500 lbs at or slightly less than 4k and peak power about 5200 also near 500 with a 750 demon and RPM Air Gap and 9.6 cr. Hard to beat those figures with a streetable small block.
