i have a 94 gt 5speed ragtop with like 170k miles on the ticker.. and i have a full exhaust, cai, a/c and smog delete,and accel cap and rotor button, and my intent is 320-400 hp just somthing to have fun with.... so my ? is what to do next, i was thinking suspension...

 

94 'vert is pretty heavy. im gonna say about 3800-4000 lbs and thats if your light. im only 150 and my '90 lx vert was 3600 with me in it.

anyways, if you do NOT have 4.10's.... do it, then spray the car with a 75-100 shot. you'll need a sticky tire after that, but for about $1000 all together youll think you added 200 hp

other than that... just save for a HCI swap
