Ok when I punch it and it get's from second to third about 3500 to 4,000 rpm's my engine heitate's like it want's to change gear's but it dosn't what the hell could this be it does not do it at any other time just when I punch it My timing is tip top and I just installed a new manifold setup TB etc. I'm missing my 5spd 91 now This is a 87 resto project with a Aod.
