1974 K10 manual options

[ih766]

I have a 74 K20, Dana 60 in the front, 14 bolt in the back. I also have a 700ish hp supercharged LSA that I will absolutely be tossing in it. My only issue is I’m having a difficult time finding a viable manual to hang behind the LSA that isn’t a headache and a half to get in. So my question is what manuals are out there to put in this old girl? Autos are out of the question.

4 speed would hold up I'm sure, but most likely not what you want.

Your only option really is a t56. You're not going to get what you want unless it's at least a full headache lol

What about these? TR4050 5 speed, with 4WD cases available. Pretty close to SM465 ratios plus an overdrive, rated for 600 ft lbs.
