[gearheadAbe]

@narutofan51593 the tv valve are fine. Is your cars Tuned port injection

[TheBears84]

very nice man,...... I have a 89 formula 350 that sounds very simailar. putting a ls1 in my 90 formula

[gearheadAbe]

@TheBears84 Ls1 would be nice. Im looking to build a 383 Stealth ram. my goal for HP will be in the mid 400s.

I drove 1 350 tuned port Fbody and wide open from 20 till around 5000 rpm it pulled verry much like the LT1 cars that I have driven many times. I was realy surprised. I thought these engines lost all of their ass after about 4000 rpm. maybe that is the cas more so with the 5.0 tpi? What rpm does your TA shift to 2nd on it's own?

[gearheadAbe]

@ztwntyn8 yes tpi has lots of low to mid rpm power. my car shifts around 4,000 at wide open throttle.
