there is a HUGE difference from a 16G(small or big) to a 20G

with such little displacement you have, i would say go with a T25, or a 14B (13G if you can find one, automatic 1G dsm)

might also want to lower your expectations...try 225whp as your 1st goal...thatll be hard enough as it is..and i dont reccomend running 15psi either...id say try 10 or so, then slowly work your way up and see how the motor likes it.


ps- saw you had a stock fuel pump...id say drop in a wally 255...the stocker isnt going to like flowing 42#/min
