1985 GT - Test your mustang knowledge, guess how fast i'll run 1/4 mile

[84LX89GT]

Cool, i'll probably just run the 1st time with the 3.73 rear axle (allegedly 3.73) with stock control arms and lowering springs, then for the next time out i'll swap the 4.10 8.8" rear out of my LX and install the granatelli arms i got with GT rear springs and see what happens.
---update, the car is running and driving and i drove about 100 miles to start breaking the clutch in----
currently needs fixing: high idle, probably vacuum leak or carburetor - won't spend too much time doesn't affect 1/4 mile. I need to swap the stock shifter in - the summit shifter SUCKS!!!!! - all gauges are erratic or just don't plain work, i'm going to make an aluminum plate for the dash and install gauges in that. - Shake at freeway speeds, probably (hopefully) just unbalanced tires.
I have phone dial wheels for the slicks and i'll mount those up soon.
Also found out (found ID on carb) that carb is a 3310 Holley 750 cfm vacuum secondary....that explains the stumble/bog at part throttle or at mid-rpm.
I pulled out the MSD distributor and found that when i got it the timing was retarted to 6* initial so it would idle at 900 rpm, the distributor curve was the slowest possible (comes w/dist) heaviest springs (advance full @ 5500 rpm) and the total advance bushing was 21* (27* total advance w/initial). I changed the curve to hit full @3000 rpm, 36* total advance with 11* initial, made a huge difference in torque and power in general.
-things are progressing but i've had to start almost from the ground up with this stupid thing
