Also you had a few specs wrong.
I had a 3.10 gear
28" tire
And it was closer to 5900

It's an s475 borg Warner turbo
I don't know what year it is. I found it on Craigs list for 300 dollars delivered, put a turbo on it. I don't even know how to tell what year it is. I has 862 heads if I remember correctly. I did have to put upgraded valve springs because of valve float above 23 psi. Right now it's at 25-26 psi. I believe I'm out of waste gate spring so I will take the 10 psi springs out and put 15 psi springs in. That should put over 30 psi if the turbo will flow enough.

Thanks, it took along time to get the suspension to work. I wasted lots of money and I'm not done yet. I'm gonna switch over to TRZ parts. And double adjustable shocks all the way around to get ready for what's coming.

Since you asked about 4.8 camshafts, there is a member on here named Dezlfreak that runs a custom grind of ours in his 4.8(it's actually 302 cubic inches as it's forged).
At 3400lbs race weight and on 15psi with a S475(should easily make 30psi on a 4.8) he went 9.50@147mph. IIRC 60' was 1.60+ and it was his first time with the combination at the track.
