Gear change update

I have had a terrible time with this 64 Falcon I bought. I couldnt get it to run any faster than the 10.20s 122-125 mph. I did change the stall on the converter over the winter.This was the same drivetrain that was in my Blue 71 Cobra Torino. We swapped out fuel pumps,ignitions, Etc . I was really disgusted and pissed off. I have never struggled so much with a car.
I also posted on here about a low ratio gear set in a C6 and some said it would hurt me but I couldnt understand why it worked good in the Torino and not the Falcon.
Blake thru up a post about a situation and alot of people responded and they said it would hurt the times. So what the heck I had a set of 3.91 gears set. This was my easiest thing to change. Well I went from 10.20s to 9.87 just by swapping the gears. My best last week was 9.87 130.00 miles per hr. I had 4.30s with a 32" tall tire. SO I have pulled the low ratio tranny out and am in the process of putting in a standard gear ratio tranny and racing this Friday. I will let you know how I make out. So I guess you can gear to low.

yep, BB dont like all that starting line ratio.................thats why the glides works so well when coupled with the right gearing and converter.

Congrats on the numbers............

514ci, 14.5 to 1 comp, roller cam and P51s ported by Charle evans, Car weighs 3550 with me in it.

I'd sell that c6 crap and stick a glide in it........................

Not right now I got 3 C6s sitting here. And I am on the austerity budget right now,

A 9.87 is good but it seems like the MPH should be better than 130 for that ET?

Later Mark.

With the gear swap its happy on the bottom but not so on the top........its laboring in high gear now.

I told him to change the gear to prove that it would pick the car up by reducing his first gear FD ratio. Now he needs to put the standard first gear ratio planetary back in and go back to his 4.30 ring gear. Wit the low planet there is a wider gap between 2nd and high that hurts the car from getting in high gear in the sweet spot. Could be whats up with the mph.

Yes I knew the gear swap was a easy experiment...............that proved to be correct...........

I am leaving the 3.91s in right now and will see what happens. I have some 4.11s and 4:30s to try but one thing at a time.
