Car is Falcon XB coupe,similar to 71 mustang weigh about 3700pound.
Engine 460,671 enderly injection running on methanol,C6 box,29 X 12 Slicks
Unsure on my diff gears,I took my car to drags last w/end first time in about 10 years.
First run did half track,
Second run I ran 10.14 @ 129mph.I had backed off before finish line as I wanted to make sure car would pull up ok,which it did.
I had done complete run in drive as (found out next day I hadn't cable tied shifter cable above exhaust & melted it)
I only saw shift light come on (6000rpm) in top gear about 50-80 metre from finish line.
After run I had blew exhaust gasket after couple bolts came loose which ended that night.
My ? is if I need smaller (3.5 gears)
Will be taking car out soon once fix up
Thanks Steve

You say you bumped the 6K limiter with a 3.90 gear and a 29" tire? I used to run a truck with a 29" tire, 4.10 gears and went through the traps @ about 6,200. That's not turning even a close to stock 460 too tight.

It was 1st time at track,was planning on gear change at 6000,as camshaft is a bit small & powerband is from 2500 - 6000rpm.I have rev limiter set at 7000.
I have steel rods but standard crank also.
Thanks Steve.
