400 (SBC)flywheel/ bell-housing

Hey guy's, i have a guy that want's to trade me a M-21 transmission for a set of factory Boss 302 valve covers i have had for several years, And what i need to know is weather this M-21 can handle 500 plus HP in my camaro, And also what would be the best flywheel for this app and what would be a good bell-housing to get also. All advice is welcome not really sure exactly what i want to get for this if i go with this trans. Oh and he has a M-20 also he mentioned trading if i didn't want the M-21. The M-20 is supposed to be like a 65 model and the M-21 is a 69 model by the #s supposed to be from a 69 camaro. Just needing some advice from you guy's on this.

Hi Cole
The M20, M21, & M22 are about equal with the M22 having straighter cut gears. The 20 & 21 are newer then the 22 & they have smaller syncro rings, but you can use the 22 rings but you must use the corresponding/correct 22 syncro hub with them. It's more then adequate for the power your putting out.

PS I think I'd use a Lakewood Bell housing.
Fly wheel? Billet SFI approved.

Cole, if this is going to be used on the street, I would suggest that you use the wide ratio M-20 as opposed to the close ratio M-21 unless you have real deep gears. The 2.20 low of the M-21 is hard on the clutch when trying to start out easy.

take it for what it's worth, get a quicktime bell...
lighter and more compact.
a little more $$$ though but worth it.

will the muncie handle 500 horses?
if the car hooks, maybe....

btw, they bring about 500 bucks on up around here...

I have seen at least 2 M-20,21s scatter their guts on the ground behind pretty stock 327s. I doubt one could take any abuse behind 500 hp.

Thank's to all of you for your input i really do appreciate it I have i think talked myself out of this trans swap, Ex-specially since i have already shredded a BW-Super T-10 with this engine I am now thinking about going with a TKO-600 or something along that line , i don't know alot about them but do know a few guy's that are running them and really like them so far. Oh and Bill i am running 3.73s with 26inch tall tires right now with a TH-350 and a 3000 converter. It will be mainly street driven after this swap might see the track from time to time well i know it will i can't help myself i love the track. It's been a while since i have had a stick back in this car and i really love to shift the gears and it being a factory 4-speed car i would just like to have it back in it.

That TKO would be a far better choice. A bit pricy, but that's what it takes to run with the big boys...

PS The other upside, you get to keep the valve covers.
