Not an expert on TH transmissions, but I doubt it.
Is this strictly a racing truck? Most folks today prefer something newer for less engine wear and better gas mileage.

what would be a better transmission? Definitely not a race truck lol… just a once in a while driver that Can be a little fun.
Yea that’s exactly what he said… would those work in a 85 with a SBC?

As long as its a Chevy bellhousing case and the length is workable it would be fine.
Buick, Olds, Pontiac and possibly Cadillac used one with a different BOP bellousing.
Any I've seen had a longer extension housing and tailshaft than a regular T-400
They were common 1971 to about 1976 big Chevy's like Bel-Air, Impala, Caprice etc.
This was in response to the too short transmissions used in 1965-70 big Chevy's.
The regular short trans in the above mentioned required a too long driveshaft.
They often experienced driveshaft failures in cars that exceeded 100 mph in the 1/4 mile.
I had a 1967 that spit out a few driveshafts crossing the finish line!
Not a pretty sight and each busted the trans case as well.
Thanks

what do you have now, what are you working with? 300hp, although formidable, is hardly fun in todays standards.
But, at the same time, nothing is a fun driver without decent fuel mileage and an overdrive.
anything from 1998 to 2013 would be a great fun addition to your S10. 25+MPGs, at least 400 hp, ac, powersteering, cruise
Theres lots to learn if youre interested
What else would I need to use that transmission?

The usual stuff and a driveshaft.
The only thing different with this trans compared to a regular TH-400 would be a shorter driveshaft.
Thanks

It depends on what your putting the trans in??
In any case you need a shaft with a 27 spline yoke to fit the TH-375.
Many GM trans are 27 spline EG: TH-350, 700 R4 etc. so that end is easy.
Then you need to determine the length and rear U joint size to fit your diff.

For what you're planning to do with the truck sounds like a 4L60E if using EFI or 700R4 if carbed would make most sense. Easily built for 300HP and will bolt in with stock mounts and driveshaft. Should be able to find a local builder who can put one together for you for around $1500. He'll need all the specifics as to what engine, etc you're using.
I want a 700R4 I believe it would be a easier setup but I could steal that 400 lol.
But I’ll wait
Thanks Guys

I went from a TH 350 to a TH 400 and we had to make a new driveshaft.
