Cam Specs is this too big a cam for me?

Hello all, It has been a long time since I've looked at Camshafts, and don't remember exactly what are good numbers for int. exh. duration and lift. The reason I ask is I've found a cam at a reasonable price that is new and wondered if it is a perfect fit for me? The Cam is a roller cam and the specs are INT=262 EXH=307 Dur= 206-245 Lift= INT=450 EXH 541. My car is a Duster with a 318 with a roller cam its a 88 motor, headers, 4 barrel intake and a 904, at the moment manual brakes. Is this cam too wild for the engine without a stall converter, as I said its been forever since I've thought about or bought a cam and the 541 seems high?
