Easiest way try free myself of my sm465
 

Ok, ok....I know...legendary transmission...bullet proof. Trust me I am awed by the beating they take and of how simple they are. No disrespect to the venerable 465.

That said...I recently put a nasty 400 sbc where a 250 one resided and I want to bang gears. My truck is a swb 69 with an original bell housing, manual x member ect.

A tremec with overdrive would be ideal....too pricey.

A turbo glide or th350....for the price I might do without overdrive and grow to like a ratchet shifter.

How bad is an auto swap.... xmember changes? Resize/ balance a shaft? Anybody been where I'm at?

Thank you in advance.

NV3500 or NV4500 would probably be easiest but they're still truck transmissions. I have a spare 2WD NV4500 but you're a bit far...

If you are down to a bare frame the swap is a walk in the park. If cab and bed are still on it's tougher BUT time and determination can accomplish anything! For a trans like the TH350, the crossmember might stay in the same place. I have never worked with your trans, though, so break out the measuring tape to be sure. For the turbo 400 move the crossmember back to the rear set of holes. Driveshaft gets shortened by somewhere near 6 inches and you will need the kickdown set-up for either auto. I run a built TH400 with a manual valvebody backed up by a Gear Vendors overdrive unit. Very nice as final drive ratio keeps RPMs to 2200 @ 70 mph with a 4:11 rear.

what might a spare nv4500 go for?

I think they are overpriced. I can't find one for less than $1500. Seems like a lot for a used transmission that's 20 years old.

Some online places sell them for around $3000 without a core.
