well with the car running like crap breaking up,.

 

With some work and a better suited converter I'll bet a ggod 6 to 8 tenths will be shaved off EASY!!!.

I know with my car the first time out to the track with the 383 was very disappointing, with some tuning and a few changes I wittled it down more than a second, and That was just with about 10 to 15 passes total.

One thing I learned is the timing has to peak a little earlier with a 383, and the lead up top has to be reduced I ran a total of 38 deg by 3500 rpm and as low as 32 deg past 6000, but each car is different and I'll bet BRE will give you a better idea of the timing curve for that cam.

The stock fuel pump on my car couldn't keep up past 4500 either.

 

yeah i was disappointed with the time but for the first pass of the year with a new setup it could be worse.

 

First times out are rarely very good....that is the name of the game.

I was expecting much better first time out (in sig)....but a smoked opti, no rpms sorta kill a car.
