    If it is a side/collum shift it would be a Saganaw full syncro 3 speed. You could run it behind a warm 350 if ya don't beat on it too hard.

    Not really sure what i'll do with. Just wanted the bell housing, flywheel , clutch and pressure plate that a guy had for sale. Basically the trans was a bonus.

    non-synchro 1st gear. Short tail. It'll handle a mild small block, but I wouldn't want to try to put too much power power thru it...

    (it is not a Saginaw, they used the old non-synchro Muncies thru 66)

    SOME RESEARCH I FOUND SAID THAT THESE TRANS WERE USED IN CORVETTES AND MATED WITH A 327 THAT PRODUCED 250 H.P AND 350 FT LB OF TORQUE. i'M PUTTING A 283 IN MY 49 TRUCK. WAS PLANNING ON USING A 3 SPEED SAG. THAT I HAVE LAYING AROUND. BUT MAYBE I'LL USE THIS INSTEAD. WANNA KEEP THE STOCK REAR IN THE TRUCK FOR LOOKS. NOW THE GEAR RATIOS FOR THE SAG IS 3.11-1.84-1.00. THIS NEW ****** IS 2.58-1.48-1.00. WOULD THIS BE BETTER FOR HIGHWAY SPEEDS THAN THE SAG. OTHER INFO I GOT SAID WITH THE SAG. MAYBE I COULD GET 55-60 ON HIGHWAY. ANY THOUGHTS?

    Yup, high gear is the same with both transmissions.

    With the saginaw you'll be able to downshift into first without having to come to a full stop (or double clutch) like you would with the non-synchro trans.

    Saginaw should be longer too. Do you have a driveshaft already?

    YEAH THE THE SAGINAW IS LONGER. ABOUT 3-4 INCHES FROM A SIDE BY SIDE COMPARISON. THERES A DRIVE SHAFT IN THE TRUCK. NOT SURE YET IF IT WILL WORK. I KNOW IT WILL NEED SHORTENED IF USING THE SAGINAW. BUT NOT SURE IF IT WILL BE USABLE. IN THESE TRUCKS THE DRIVE SHAFT AND REAR IS A CLOSED UNIT. I THINK I SHOULD JUST CHANGE REARS AND BE DONE WITH IT. HERE SOME PICS OF MY PROJECT. A FARMER RAN THIS TRUCK TILL 1993. THEN PUT OUT TO PASTURE TO DIE. I GOT ABOUT A 1 1/2 YEARS AGO. GOING TO TRY TO RESERECT.

    If the rearend is the closed driveline type, then you'll need a different rear and driveshaft to work with either of those transmissions.

    Yep Squirrel you right -me wrong on years used. Don't know what I was thinking er THINKING that was the prob.

    49 Chevy :Use the Saganaw a lot tougher than the early box. Years ago had a 300 HP 327 in a 59 Vette and tied them things in knots, finally gave up and stuck a Munice in it. Matter of fact that that basic box dates back to 49 and my 261 Chev 6 blew up a bunch of them also.
