What is the common manual tranny to put into 2 wheel drive cars or trucks with around 400+ hp/tq ?

Hell yeah, Lenco is the way too go. Need anouther gear, just add another section.pauly383k10 said:Steve , go get a "Lenco"

trucks did not get 4 speed car side loaded trans
three speed yes, but not four speed
i think yo should research and learn the basics of gm manual trannies first, or its gonna cost you and youll be running into troubles with spline counts and so forth

Straight cut gears, stronger, Plus with the M22 you get a crazy gear drive sound. Nothing like the sound of horsepower coming out dual 3" flows mixed with the whining of the tranny in first gear cruising up your street at 2500 rpm. It whines loud in first, second a little quiter and by the time you are in third and forth, you dont hear it at all.
Guess I should just put the coils and front bushings back in 

Remember the Vega GT? It came from the factory with a M21 Muncie 4 speed. The regular Vegas had the Saginaw 4 speed. Probably the cheapest GOOD 4 speed you could find in a junkyard would be one of the GT Muncies. I put one in a SWB 70 GMC years ago, and it bolted up to the 350 bellhousing and the driveshaft yoke even matched up.84gmcjimmy said:AH! With the forum change, I guess my reply got deleleted...
Where can I learn more about GM trannies? I don't want to run into trouble, so I better learn first. How many speeds are the muncie trannies? What vehicles did the muncies come in? What vehicles did the saginaw cast iron come in? Any more info is great, I'm just sucking it all in and learning! THanks!!
I'm not building a muscle car or whatever, I could only wish. I am just explanding my knownledge!! haha But yeah, eventually I want a muscle car!
Alright thanks for the info.90blzr said:Yup, that be it. Bad ass. Thats a fair price also, I'm sure it will get higher. I guy hit me up a while back to buy an M22 in excellent shape, the tranny, shifter, pressure plate clutch, everything for $600. I lost his number and havent seen him since![]()
There are other aftermarket trannies too, Doug Nash 5spd which I was considering, but would have had to do some mods to the floor. Then you have the Richmond trannies, Borg Warner, etc.
I have no complaints on the M22. Like I said, the whine sounds sweet. You wont fully understand what I mean until you here it....some people like it, some dont, kind of like the hum of swampers, you either love it or hate it![]()
Okay I will keep the GT in mind. Thanks3 on the tree said:Remember the Vega GT? It came from the factory with a M21 Muncie 4 speed. The regular Vegas had the Saginaw 4 speed.
