I put a 350/700R4 in my 64.
I originally had a 6 cyl and manual trans.
My original trans crossmount had to come out and I had to pick up some V8 engine mount brackets.
You will have to shorten the drive shaft and mount a new trans crossmember for the 700R4.
Don't forget to wire in the overdrive through your brake system.
Also don't forget the radiator will need to be a bit bigger
All and all not a hard swap.
The wild card in the deck is that mine was a 1/2 ton and you are talking about a 1 ton truck. And that I don't know about.
