hi guys i've been working on my 91 gta trans am and need the opinions of this message board listed below are the upgrades me and my friends have been compiling together for the past year to make this gta a beast. I hardly see any 91 gta's in chicago so this summer it's time to let them know we've finally awaken the beast. However, there's been speculation on how much horse and 1/4 mile times we're going to get out of this baby........please tell me your estimated hp and 1/4 mile times this setup will give us:

accel intake
accel superram
hooker long tube headers 3"
accel 36 or 34 not sure lb injectors
350 block, bored (.60) over
crane cam 534/554 110 sepration
crane cam golden 1.6 rocker arms (hydrolic roller rocker converstion kit)
3500 stall converter
th400 trans
msd 7plus ingnition system
moser 12 bolt 3.90 gears
b&m manual valve body shift kit
msd 8mm wires
msd alternator 160 amp
B&m 58mm throttle body
rattler harmonic balancer
edelbrock angle pluged performer heads (60cc's) competition corvette heads

I appreciate the responses and thank all...................

 

Bored that much over, not very fast because the pistons won't have anything to ride up & down in.

Now, if you went for a reasonable .030" clean-up or last-ditch .060" hope-I've-got-some-cylinder-wall-left overbore, then it'll probably be in the 13's, maybe 12's after getting it sorted out, with those modifications.

I don't know why you'd need 36 lb/hr injectors. I doubt it will have very good street manners, if that's an issue.

Why?

 

sorry glitch .060 was what I meant to say and the injectors are 30lb. need the alternator because I'm putting a system in the car, but do you think I can hit low 12's.

 

It sounds like you're building a multi-purpose car that compromises both purposes. But, I never was much of a boom-box kind of guy.

You haven't said anything about suspension mods. Without traction, you aren't going to hit the 12's, let alone low 12's. Making the power is only the beginning, getting it to the pavement is usually the harder part (along with keeping it together).
