It all depends on the build, transmission, tires, etc,

I believe the banjo is good for about 350 HP and 350 lbs of torque. I ripped the banjo apart in my 59 gmc 1/2 ton with a mildly built Pontiac 389. My 389 was built for about 345 HP and 450 lbs of torque.

Put it together and see if it will live.
