5.3L w/ manual transmission - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I love driving manual transmissions but I know jack about them. My '50 has a 3 speed on the column but I would only run that with the original 216 as a show piece. That's not in the plan.

What is in the plan is a 5.3L that is collecting dust in my garage. I want to mate it with a 4 or 5 speed transmission. I think it would be fun and unique plus I want something that can drive anywhere. After a little research, it seems that pretty much any transmission can be made to work with the right bellhousing, clutch/flywheel and throwout bearing assembly.

I don't want to spend a fortune on this, it's not a street rod so the T56, TKO and other higher end transmissions are out. I have thought about these:

99+ NV3500 (came with 4.8L's)
98- NV3500 abundant
70's or 80's 4 speed OD truck trans
Jeep AX1500
close ratio Muncie 4 speed?

I will find a rear end ratio that is best suited to the trans, not opposed at all to running a 4 speed with 1:1 final drive if it's cheap and available. Anybody done something like this or thought about it?

Not running a 5.3L but a 327 and using an '88 NV3500. SO far, so good. Hardest part was the bracket for the clutch...because I had the hole in the wrong spot so the bracket we built had to be rebuilt...because I'm an idiot.

Dan, do you have any pics of that? I'm thinking about the lclutch inkage and where the shifter comes up...

Well I found a local guy with what he says is a 5 speed from a '98 3/4 ton 2wd for a very reasonable cost. I'm going to look tomorrow, any idea if this could be NV4500 or?

I'm planning on putting in a nv3500 out of a 91 chevy into my truck. The one you're going to look at is probably a nv4500. My 350 is a pretty mild build so I'm not worried about the nv3500 holding up in my truck.
