This was at Rockingham, the same place Jonescap ran his 11.77. Today Jonescap ran an 11.78 at Fayetteville, a completely different track about 100 miles away from Rockingham.

Yes; the plenum, runners, and base have never been removed from the car. They are 100%, non-ported, as installed by GM. As far as I know, my NA time is the fastest non power adder stock TPI manifold time there is. I'm also pretty sure that I'm only about .05 off the mark for power adder and stock TPI intake.
With any luck, on a 150 shot, I might be the fastest stock TPI intake car there is.
Thanks, it does run pretty good.
It only made 230 RWHP with long tubes and no tune, so I don't think it's a factory freak. After I tuned it, it made 261, then 270 once I added 1.6 roller rockers.
The 4-5 shift does suck, but hopefully I'll swap out the intake soon and be able to rev it past 4800.

Must be a factory freak...
