Awesome. Looks like a great project. I just started the same project just about. What numbers do you expect to have?

Re: LE 383 is done!! Sound clip

Sounds pretty good, I have some clips of mine that I need to get uploaded, doesn't sound all that different. I would think 420-430 through the 12 bolt is definitely not out of the question. I put 413rwhp SAE through a 35 spline 9", 3.5" steel d/s (.090 wall), and the heavy stock WS.6 rims. And thats done with ported stock castings that flow 270/192 @ .600" you have more lift and more flow and a more efficient rear end. Just get it tuned well and be sure to post up the numbers.

Re: LE 383 is done!! Sound clip

MADZ28 did the OBD1/baseline, and I have tweaked it past that with tunercat to get the last 7hp out of it.

Re: LE 383 is done!! Sound clip

The baseline was great, I have just done a little part throttle to improve gas mileage, and did a little PE tuning on the dyno to get it zeroed in. I am running closed loop, but I am probably going to set it up for open loop at idle due to a false lean that won't go away.

Congrats, sounds like the car is setup to run very well. Do you have a roll bar yet. I'd expect that car to run some easy 10.50s! Get that thing to the track.
