2019 summer race.... Jadaharabi vs 318willrun

How much will the transfer case take in my '85 Ramcharger? What if I built a 450 hp 440 with 500 ft lbs of torque, raced it in 4 hi ??? I think the '85 has a NP208 aluminum case.....

I guess the winter is getting to me... :D
.
I think the 85 has an aluminum snap like a twig transfer. The 77 would have a 203 which was used behind about everything from a slant 6 to a 440.
41 and rising.
