Any issues with running a '59 Saginaw 4 speed transmission with a 350 V8 versus the original 283 V8? I know the Saginaw is strong and I believe should be able to handle the increased horsepower and torque. Thanks for input.
I have a 1970's (?) Saginaw 4-speed in my '56 3100 with a mild 350 and it work fine, but I don't abuse it either!

Mike, what difficulty or mods did you have to make to get the Saginaw in there. I've got a Saginaw out of a '69 chevelle that I'd like to put in my truck, which is a '55 series 2 3100.

I didn't have to do any real modifications to put the 4-speed Saginaw (Camaro trans) in my 1956 3100. My 350 has a V8 truck bell housing so I'm hanging the Saginaw off the back just like the SM-420's were done. I installed a T&F Shifter that puts the shifter in the original 4-speed location with only a little trimming to increase the floor hole opening.

A few of my competitors on the dirt tracks ran Muncie 4 speeds behind beaned-up 350's with few, if any problems. Hammering on and off the throttle at 3-6K RPM several times a lap with the transmission in 2nd. gear had a habit of showing up weak spots pretty quickly. The aluminum case Muncie transmissions would handle 2nd. gear that way, but if somebody tried to use 3rd. with a lower geared rear end, the case would split wide open after a few laps. The Saginaw has a cast iron case, and appears to be much heavier and more durable than the Muncie. That's a misconception - - - -apparently the gears and synchronizers are a little weak. Jerry

I know this thread was originally started 16 months ago and the last post was 14 months ago. I only wanted to say that interior pic shows a clean setup. Nice work.
Can the original emergency brake be kept when using the Saginaw?
I just pulled my SM420 which had a dowel about the diameter of your thumb that the Emergency brake lever pivoted on. The Saginaw of course lacks this provision.
