4BT in a '49 4400
 

Hello, I am thinking of building a '49 Chevy 4400. I am thinking of putting the cab on a F350 4x4 frame. Looking like I will use a 4BT. My have a few questions. I am thinking of doing a 4-6 inch lift on it with at least 36" tires Will a stock 4BT be able to turn these tires at 80mph? I plan to use the factory Ford manual trans in the truck. If the motor wont be able to do this, what needs to be upgraded on it? Thank you.
