im getting one from my cousin it came out of a 63 impala super sport just wondering what the price tag normally runs on one of these

 

What are you planning on putting it behind? It's not a 63 trans. The TH 350 didn't come out until 1969.
Any used trans to me would be a core. I wouldn't give more than $50 for it.
If you want to use it in an Olds it won't work unless it's a universal bell housing.

 

cool i was buying it as a backup for my 307. my kin told me that it was rebuilt with 1000 miles on it but he says thats the story from the guy he got it from. he said i can have it cause he just bought himself a 700.

so there are some 350s that are universal bellhousings because i stumbled across an 83 cutlass supreme with an olds 350 and turbo 350 for 400

 

I can't remember a universal 350turbo. I have seen a 400turbo that was universal. Good luck on try to find one. Chevy had there different pattern from Olds, but Olds, Pontiac, Buick had the same pattern. 350 didn't come in 83 Cutlass supreme only 307 Olds. or maybe a 3.8 v6 Buick.

 

Yes, there are "unisex" TH350 cases, but they are relatively rare and were only made in the late 1970s-early 1980s.

 

yeah these "unisex" trans ar mostly in olds cutlass 77 trough 82 and buick park aves.. i would never run one if i had a built up engine the bolt holes are to close together and crack between the two sets(I put a chev 350 in an 79 cutlass drove for awile and noticed a vibration checked the trans and 2 of the six bolts remained the holes cracked and the bolts backed out)
