It can be done, and if you know how to port them and run on E85 you can run 10.80s all motor.

From the builder:
Combo is a 302, notched stock pistons, freshened with a few tricks, iron gt-40 heads, sissymax intake, 24 lb injectors, tf stage 2 cam. Compression is over 10:1 with lots of milling, 355/354 at the wheels

I think it's gonna be tough for you to hit 11's with those mods. I have similar stuff on my 89 GT, as you can see, below. Dynos roughly 290 at the rear wheels, and only ran 13.2 @105 on street tires, with a 1.91 60' time. Mine is carrying a little more weight, as it still has all of the comfort features intact, i.e. a/c, radio, etc., etc., etc. I figure a set of slicks would take a half second or so off of that time. Admittedly, I'm not the greatest driver, as I've only made nine 1/4 mile runs, but, I think it's going to to take John Force behind the wheel and a strong tailwind to get 11's. I'm thinking you'll run mid 12's on your slicks. Good luck!

haha not sure if its my driving is all that great but im far from worried about breaking anything so i leave with the foot to the floor and just bring the clutch on fast. 2step was at 4500 might lower that to 3500-4000 to see if it helps give me a second to my mind on going into 2nd. at 4500 as soon as i had the clutch all the way out it was back in

Getting the 11's should be doable. My 82 got to 12's with some similar stuff. Took out everything to cut weight, 4 cyl springs, alum bumpers, alum d/s, etc. Has old iron Gt40's with a small cut, good springs, etc. I do have a C4, 4.10s, etc. 7.5 axle, and BFG Drag Radials. 600 Holley vac sec.

Took some practicing but it got there. Have not changed the combo in 5 years due to work. Roll bar added 80 lbs, so it slowed down some.

I knew it wouldn't go 11s first pass out but it gave me hope that she'll run the number when it cools down . It was it in the mid low 90s last night for that pass.Going to pull some more weight out then try and find the 24s I have for it. ( moving sucks! Not sure where that box is)
