OK, so I might be posting in the wrong forum, but I know I can get an
answer here..
62 Ford Country Sedan (wagon)
dropped my 351c in it with a 4R70W behind it.
and I left the stock rear end, leaf spring setup.
Now I leveled the engine, front to back and side to side
using the carburetor base.
I have a 1 deg neg drive shaft from trans to pinion...
does this sound OK?

Now I have read many, many drive train sites, and some seem to
contradict others. Some make it seem like you need advanced
computer skills, hell they've been doing this for ever...
My measurement was take with the car on all four tires..

May depend on the pinion angle down and pinion/shaft positive degree up on the install.
Taking into consideration rear diff rotation due to the engine torque load which changes at a steeper rate than the trans angles, on the degree of positive set needed at the trans,, I'd just make sure the trans yoke/joint angle doesn't go to negative. My .02

 

I think this is one aspect of the car that I will leave to the experts, and take
it to a drive train shop. I've got a shop not far from me...
Thanks for your input...
