and the GM847 with 1.52 rockers and BBK shorties?


The car has 3.73's, SLP CAI, a cut-out, and a 2800 stall converter and dynoed 262/292 with a slipping tranny.

 

360-370rwhp I suppose

 

Hopefully I will have this stuff done some time nest month, I have everything but gaskets a vented opti and rockers.


I was hoping to dyno a little closer to 400, we will see.

 

Not going to happen with BBKs. Those are about the most craptastic header available for an LT1. With a big setup like yours, that's no good at all

 

Is your trans mission still sliping? I would expect 350 provided you have a good tune and your trans is no longer slipping.

I would ditch the BBK headers. I dont like anythink that BBK makes. I guess its there quality. That I dont like

 

BBK's are not on my car, but I am getting them and the y-pipe from a buddy for $150, 'cause he just got a set of LT's. I can not afford LT's right now, so it's BBK's or stock manifolds.


Trans is no longer slipping, had it BUILT again.
