Well to say this I met a guy at the dyno the other day with a 383 LT1. He had a very low lift cam in it, like 520s, and some shadetree mechanic ported heads on it. I talked to him about what hes expecting to make, I had just dynoed my 408, and he was saying should be about 500 on motor. I told him noway in hell hes making anywhere near 500 on motor with that setup and he looked at me like i didnt know what I was talking about. Well low and behold what does he make?? 320 rwhp on motor and about 450 on some shot. Moral is just because its a big motor doesnt mean its going to make alot of power or run well. My 408 made more on motor than he did on spray.

its in a 97 camaro and to the people saying "it depends on what he has done to it" He told me cold air and exhaust. Does a 383 have to have a special set up or something?

"It all depends on the setup" means more specifically what kind of heads, how big of a cam and what compression he's running. Without knowing that, he could be making 300 rwhp on stock heads/cam, or 500 rwhp with big heads, huge cam and 13.5:1 compression. CAI and exhaust are relatively small factors in determining how much power the car is going to make.

LOL sorry man, my post should have read this way:
I agree. Aaron 653, read my post again. I was kind of in a hurry when I posted that and should have been more clear.
