I had TPIS Big Mouth manifold, large tube runners ported plenum, 52mm TB and chip on a mild 383 in my '87 GTA/700R. The low and mid range was excellent, (1.86- 60ft times, 13.35 at 104, 3.27 rear ratio, car/driver weighed 3600) but it was all through at 4800 rpms. I am sure the mild cam contributed to that too. I believe it is tough to get any tube runner system to make power much above 5,000. Maybe Extrude Hone porting the runners and manifold would help.

The car ran consistent 13.35's at 104 with 1.85 60-ft times. Great low and mid range, I shifted at 4800. I am sure the mild cam contributed to the that. But it was a reliable, torquy engine.

TPIS runners are ASM. When I called ASM to purchase they said they were out of stock but I could get them from TPIS. I did and I paid $100 more for them. I used SLP on my 86 and there was a real improvement in et over stock but I can't directly compare them to others. I will say that the SLP casting is large and this makes the install a bit more difficult. I really wish I had tried a mini-ram.
