How well do y'all think the 4l80e will handle 5 ton running gear and 54 inch tires. The gear ratio is 6.44's and I'm unsure of the gear ratio in the transfer case. I do no the transfer case is a regular 5 ton case. I'm looking at making 4- 500 hp on a 383. what will need to be build in the tranny for it to handle this kinda power
