Rebuilt 727 with Transgo stage 2 shift kit
Standard 360 stall converter

9" with 3.5:1 gears 275/60 15 MT ET streets

First time at track:
14PSI 12.1 @ 119mph
17PSI 12.0 @ 122mph
20PSI 11.9 @ 126mph

Standard stall converter was not big enough and i could not take off with any boost, so all my 60 foot times were 2.0. I have just put a 3500rpm converter in it and will go out again. I think on a hail mary pass it should run a high 10 if it doesnt grenade first!

Car weighs approx 3500lb+

Cam idles like a baby, plenty of vacuum. Makes max power @ 5500rpm

Any more questions please ask.

What fuel? Intercooler? Meth injection?
