I have a 1983 Scottsdale 4X4
I just acquired a 454 stroked to a 496 big block with a B&M blower. My question is will it bolt up to my 350 turbo trans and is there motor mounts made that will let me install this big block in this truck.

Welcome to Chevy Talk!
It should bolt up to your 350.
If your truck was a bigblock originally,it will fit.
If it was a smallblock originally,you'll need to find the big block clam shells.They are about 3/8" higher than the small block clam shells.
If you try to use the small block clam shells,your big block fuel pump will sit on the crossmember.
If it's fuel injection or remote electric fuel pump,either mount will work.

"You gonna leave it like that?

Wow!! Upgrade the motor and transmission mounts to polygraphite. The mounts are stronger than stock and will help put the power down. Eventually, the 350th trans will need upgrading. What is you planned torque converter stall?
