im building a 383 with the cc306 sence everyone side my cc503 was to small, would like to see what others are puting down, with this setup.

 

I've got that combo with a 52mm TB, Hooker LT Headers and pcmforless tuning + my own pcm tweeking and I'm running right high 11.9 times on stock fully ported heads matched to that cam on 1.6RR. That's on 1.6 flat 60' times. So if your not set up with good sticky tires to run those times and a good rearend don't look to hit the 11's with that cam. It's a realy good street cam with tons of torque down low. If you want more up top I'd seriously go with a Loyd's LE4 cam or at the least a LE3 cam from him. A cc306 is awsome on a 350 but a 383 will tame that cam WAY down. It's good for me cuzz I can DD the car on that cam with no problems and I plan on shooting a 200 shot to it soon since it's rather decent for nitrous given the large exhaust duration.

 

yeah my car is a DD so i didnt want to go any bigger on the cam i just bought the cc306 last night everyone says a good street cam for 383, i want 11s on motor i think it shouldnt be a problem i have M/T E.Ts 26.0 by 10.5 and 3.73 and 3500 stall and all the mods in my mod list plus im going to get the heads ported and 2.00 1.56 valves or 2.02 1.60.
