damn, good #s. Your build is very very similar to mine, i have a 402, and the same cam on a 112 with 2* advance on the chain. I also put 452 rwt, but only 462 rwhp. I dunno what the hell is wrong with my setup. I only ran a 12.3@112 on sunday with the motor and 11.3@125 on a 150 shot. The more posts i read the more pissed i get. I am having another tuner look at mine. There is gotta be something wrong, pulling timing or i dunno. Anyway great #s, get her to the track.

 

Nice numbers! Can't wait to see some track times.

 

Yikes, something is very wrong with that setup.

 

Sounds like a very nice and fun 383.......good numbers!

 

Wow nice results. My buds 383 made 500hp 460tq on a stang dyno. These motors have come along way.

 

I really don't have the tires to get any good results at the track right now. To do it right in a vette you should really have a drag pack setup to take up some of the shock on the launch. The car has been down for a bit lately so I just want to enjoy it while everything is running well.

 

Weather around here isn't the best right now for good numbers, but you should have SAE correction anyway which won't help at the track. Just go through everything and make sure nothing is left on the table. I've probably got 4 hours porting the intake and tb, time matchng the heads to the intake, making sure my exhaust manifold gaskets didn't protrude into the stream, aligning exhaust flanges, etc, etc. It's the little things that turn a average setup into something special IMHO.
