Also I will be putting in a 700r4.

a set of 305 vortec heads and matching intake would make big gains in airflow,compression and match your cam much better.
a 2500 stall conv and 350 rear gear ratio would really wake it up

with your combo your going to gain approx 30hp

with the combo i mentioned i bet you get 80hp

do yourself and ppl around you a favor give up 5 of those hp and weld some cats in it please
