Question Muncie Trans question

Hello,I have a '69 Muncie M-20 (case 3925660,ID P9D15A) that is in need of parts replacement (1st gear, input shaft, and counter gear). I have seen some good prices for complete M-22 gearsets available. Is it possible to convert to the stronger gearset without any additional purchases? My application is a street/strip '69 Camaro convert. with a mild (400hp) 396 and 4.11 gears (12 bolt) running 9" ET Drags in strip trim. Has anyone enjoyed reasonable reliability with a combination such as this? (Full M-22 gear sets are available on E-Bay for $685, cost for my standard repair is $325. This is what piqued my curiosity.)

I am no tranny man but I would think that in a sweet setup like it sounds like you have, you would want a close ratio tranny such as a m-21 or m-22 close ratio
I wouldn't be surprised if , with the correct parts, you could convert the 20 to a 22, but the best thing to do is go to a local trushworthy tranny shop and check with them. Most shops will have someone there who can rebuild them and who can give you the info you seek.
Good luck!

it is not cost effective, the price of all new M-22 gears would be prohibitive.

Hi,thanks for the input. I received a message from Larry at D&L Transmissions. The Muncie will hold any gears set with a 1" mainshaft. A 1st gear blowup like mine will often lead to an out of round rear bearing bore indicating a terminal future for the trans case. I'll measure for out of round and make my decision. Thanks.
