VF! with that combination you have mentioned should make close to 500 That depending on the head work. Yes A solid cam would be good but with the clearance ramps is just a bit smaller than the numbers suggest. That is still a relative large street profile but.The lobe separation will determine how lumpy the cam behaves.Most large cams are on a 108 or smaller lobe sep to make real top HP but a wider lobe sep calms the cam down with a little less low to mid HP numbers but these strokers are torque monsters and you would never notice the torque loss on the street.
