Im building a 1990 GMC RCSB with a 9.5:1 370 with out of the box AFR 225's. Im getting with Martin at Tick for a new cam for it so the cam is still up in the air.

I picked up a Borg Warner S400 80/87 built by work turbochargers with race cover for a pretty good deal. I have both a T6 1.0 a/r and T4 1.10 a/r housing for it.

Im thinking I need to go with either the 92mm or 96mm wheel for it. What are y'alls opinions?

With a 370? Go big or go home.

Depends on the goals of the truck. Obviously your going to make more power with the 96 but what are you trying to do?

Im working on it. I had some issues with the suspension and had to pull it back apart. I will get it up to you as soon as possible.

The truck is mainly just gonna be a fun street toy but I would like to get it into the 9's if i can.

i think the t6 can get you in the 9s if the rest of the truck works well. But if it wouldn't be that big of a deal to get the 96, why not?
