not with that Unifail running how youve described it. also you dont really rev highenough to warrant that .82 either. if you had a built AEB(or a true 2.0, 83x92.8) with atleast CAT 3651’s i could see having a larger housing since you could rev to 8500 or so, but on a stock cam small port head, .63 would have been your best bet.
oh. also changing axles gets old, i wish you luck.
