ok guys, I'm workin on doing some upgrades on my 91' RS. I just want it to be daily driver friendly for now and want to have a little weekend fun with it at the local dragstrip, while I'm currently building a Turboed Lt1 to take the old 305s place. Here's what I have to work with, the car is a 91' rs with 108k. of course its got the 305tbi w/ the 700/r4. So heres what I got

3.90 gears
completely rebuilt 700r4
Stage 2 shift kit
hughes 2500 stall converter
k&n open element
Lt1 cam
comp cams valve springs
gm parts timing chain
Long tube headers and aftermarket cat back
will be running 16'' iroc wheels
255/50/16 dr's
1.6 roller rockers
Tune
also have fiberglass hood, no rear seats, and no front or rear bumper supports.
also will be running a 100 shot at the track.

based on these mods what kind of times do you guys think I could pull?

 

convertable right?? convertable is a little heavier...
estimating is always fun....please post your times when you actually go so we can see how close we all got.....
my guess is.........high 14's low 15's on motor, and low 14's, maybe if lucky 13's on spray....

 

Sry the car is actually a t-top car w/ lexan tops. I have an 88 iroc ragtop project car so thats where my name comes from. O and the suspension will be 100% stock for a while too.

 

oh...that's helps a bit...but I'll stick to my times.....305 TBI motors are not known for making a lot of power....but then again a good 14 sec run would not be bad on a 305....you are talking about the 305 and not the new lt1 right???

 

yes still talking about the 305

 

I'm gonna say the above is prolly bout right. High 14's on motor maybe high 13's on spray.
