street 383 build questions im looking to push the envelope on my 383 but i still want it to be streetable. it will have around 12 to 1 compression. right now it has the gm847 cam in it but i would like to go with something bigger to really get some power out of it. i was thinkning 238/246 duration .595/.595 lift 109 lsa. how would that sound/ run with some LE2 heads? i would like to here what you guys are running. thanks!!

I've been seriously thinking about dumping the one I have for one he suggested.

I've got a CC306 in my 383 and it has excellent street behavior. It's a nitrous setup so i'll probably keep the LSA a little higher but wouldn't mind having a little more aggressive cam if I ever change it in the future.

What kind of rwhp/rwtq are you guys with 12:1 383's making with the 847 cam? I'm asking because I have 2 hr cams right now the 847 and a custom comp 230/230 - .560/.560 110 lsa 1.6 rr's and I'm wondering which one to run in my dd 383 m6.
Which of these cams will make the most hp/tq with the m6 full chassis and suspension work including an S60 rear with either 3.73's or 4.30's, 3" true duals, ported heads & intake, 58mm tb and 42# Racetronics injectors.

I run a weenie 226/234 .568" on a 111 lsa matched to my LPE/E.B. Porting 2.00/1.56 valved LT1 heads in my 11.2:1 383...DD all over the place and ran the numbers in my sig consistently last year with 4.10s/28" DR and a mild Vig 3600...Have since restalled to 4000, added a Spohn pro series rear bar and stepped up to 325 50s from 275 60s...There's a 10 second pass in ths thing yet, even at over 3600 lbs...I like smaller duration cams with larger lifts, always have and have had great success with them...
