Nice truck build you got going on there!
Get home safely and enjoy the truck!!!
BTW is your engine built to run and pull from very RPMs?
Reason for asking is you said you want to keep your 2.73 toghether with a 700R4.
I have the same rear and trans in mine and even though it's a 400 engine it barely makes it with that driveline.
It's the first thing I want to modify on my truck.
Keep us informed on the build
