should i hit 13s with this set up? and what are the rwhp looking like with this set up? thank for the help this site is awesome lots of helpful peeps ty portmaster for the info

 

do some suspension upgrades and something to the auto and youll go 12's

 

would a shift kit help? if so do i need a stall convertor?

 

Like Lucky said, do some suspension,upper/lower control arms, and some tranny work would def. help for sure. With all that I dont see a problem with 12's

 

I'd put a stall in it either way

 

a shift kit will make a huge difference. do that at the very least. if you can afford a stall, go for it, just dont buy a cheap off the shelf piece of crap. they never stall as high as they say they do

 

so how much hp should i be around deff 300 right or no?

 

should be around 270ish with out nitrous, and then probably close to 400 with

 

you should be more concerned with ...what ET will it run lol

 

true the ET is more important im thinking 12s with stickies, shiftkit and maybe a converter
