a superram/miniram, nice set of heads, 4l80, and 12 bolt would be awesome on this thing. when he was upset with it, i tried to buy it from him but he wanted a good bit for it.  |
That pump is only good to 70 PSI and flow drops dramatically as the pressure rises. If he has enough injector, he could try to lower the base pressure to 40 psi and see if that gives it some help. He's likely in the 60's psi with 16 lbs and that can stress a 255.
I love old TPI stuff. I could talk it all day.
