Guys, I'm late to this discussion, but hope I can add...
Top notch rebuilt Muncie should be around $800. I'm quoting the price at Old Man Engineering in Buffalo NY.
I just dols an M21 they did for me for 750. Buyer got a 1 yr parts warranty.
Whats the difference between the $400 rebuild these guys do ( assuming no major parts required ) and the guy who buys a $150 kit and swaps in new parts.
This was a 65 unit 7/8 countershaft. Two ways to go here. If the unit is good ( as mine was) they oring the countershaft bore and then set the countershaft by pinning it. All clearances are checked and the tranny is essentailly "blueprinted".
Or you can go with a 1" shaft and rebore the case. This allows you to move the gears closer toghether. I hear these jobs get a nice "whine" out of them.
Anyway, there is a difference in rebuild quality, just as in engines.
Having said that, my old M21 they they jsut rebuilt and came with my car, was missing a part causing 3rd to whine. I prolly would;ve missed it if I did the work myself. At any rate the point is, I beat the frickin tar out of that tranny and the old, missing ring Muncie never hiccuped. I mean dumb stuff..
( like 550 hp of L88 at 5000rpm clutch drops on slicks ).
So go figure...
Put my OME rebilt unit up on ebay with a 700 reserve. Yeah right, rebuilt Muncies there are 400 tops.
But if I need to drop at a high rpm on a real sticky track, or just the standard powershifts at 6800, I like to know my tranny was put together with the same care as my mill. Not just new parts put in. You dont want to doubt the gear. You want it bullettproof.
