What cams are you 383 stroker guys running? I have been toying with the idea of building up a little street/strip "weekend" car. I have access to a 383 rotating assembly pretty cheap, and I have some ported stock heads that flow ~305 @ .600 IIRC. I want to keep a reasonable idle (<1000rpm). The compression works out to be ~11:1, and the car is an A4 with a SS3600. The car will also have most of the bolt ons.
I will likely consult a cam expert when actually designing a camshaft, but I was wanting to see what some of you 383ers were running, what kind of HP/ETs you were running.
Any recent 383 builds? Since I bought the C6, I have been out of the heavy modding game, so I am a little bit out of the loop with LS1 builds of late, so any input would be appreciated.
Thanks, Shawn

I was running a Futral 239/243 cam with Dart 205 heads making 486 rwhp 475 rwtq. I am waiting to get some new numbers with my bigger cam, and better flowing heads.

Why bigger? Is the cam too "tame"? How is the idle and driveability? A4 or M6?
My car is not a DD. The motor runs so smooth you cant tell theres a cam in it. But when you listen to the exhaust note you hear the cam. It sounds healthy but not radical. My car is a M6. I can cruise at 1400rpm in 6th. Just dont expect alot of acceleration.

Before you blame the tuning, i've had numberous logs and tuners look at it, and they all say the same thing, it's the overlap in the cam, not the tune.
I'm not unhappy with it, its just "tempermental".
