No, 2spd powerglide which kills short times. If we go to a 3spd TH400 it would pick up about a .10-.15.
I am sure the 6sp is a hairy ride and you have 400lbs on us. But with an extra 700rwhp, I'd think you would run more than only .5 quicker than us.
Dont get me wrong... I am not trying to say anything negative at all.
Its a killer engine for sure. I just feel your vehicle set-up still could be tweeked to get a little more from the whole combo.
And by the way... thats more than impressive for stock axles and trans for sure ! I'd love to see the old stock Camaro 10bolt hold up to a 5,000rpm trans brake launch.
