360 smogger or not??

Hey guys,got the cam specs.It,s a Crane cam part#150062 grind#284H it has a 480 lift/284 duration.I,m gonna get a Trans-go TF-2 kit installed,the tranny(904) is a fresh rebuild.Am I gonna need the 2500 stall on top of the kit or will I just be wasteing money?Any advise before purchasing would be great.Thanks
