I ran an 11.40s with my 73 Z and the original M21 back in the day when I used to drag race it almost every weekend. Still works perfectly.

What rear gears? I think what clutch is in front of it would have been a better question.

Re: munci capability through quarter mile
 

If you want to know the ultimate strength of a Muncie, and if it will survive in your particular car, you might as well ask how many angels can dance on the head of a pin.

What clutch?
What gear ratio?
Vehicle weight?
M20, 21 or 22?
All factory gears, case, etc, or upgraded aftermarket parts?
Tires?
Chassis set-up?
How much of the gearbox fatigue life has been &quot;used up&quot;?
How hard is the launch?
Does it wheelhop?
etc, etc, etc....

The simple answer is to go to the track and find out. If it breaks, fix it.

</div></div>Here are some pics of my m21 input shaft as you can see the splines are bent and close to breakage.Dint even make to the track.By the way it was a less than 300.dollar hays clutch and a stock balanced flywheel with a 3-73 rear.This was in a 70 nova with a small block.Dint damage the tranny made alittle metalic noise. when I took it apart noticed 3and4 gear knocked the snap ring off the main shaft due to the sudden load.Thats why i started this thread.Was just looking for simple input from the more experienced and the people that bought these cars new.Good thing i didnt drive to the track because the hook would have cost me 5or6 hundred dollars for transportation back home.Thanks marc. https://www.yenko.net/ubbthreads/pics...0604-img_1.png

4.56 at the time. 3.73 currently, I dont drag race it anymore. I tamed it down, smaller cam, dual plane intake, smaller carb. I also recently put in a 5spd tko600

I have been 10.40's with a stock M21 behind a 396/402 BBc. 4.56 gear 9 X 29.5 slick in '69 Nova. Had a Ram clutch with 3 pads, not a mild clutch, just something we put together for a mild streetcar.

Put the wheels 3 feet in the air and streetrace/beat on weekly for 2 years. Sold it complete for a powerglide set-up.
