I am putting a 50 Ford flathead in a Brookville 32 style frame. I have put on the truck water pumps with the wide pulleys to get the correct motor mounts. I also have picked up a wide belt crankshaft pulley but the back part of the rear pulley will interfere with the timing pin on the front engine cover if I install it. Question is, has anybody just cut down the back pulley sheave to clear the timing pin?? If so how careful do I need to be regarding balance of the cut down pulley? I that works out then I guess I can get a generator from a 49 Ford and swap pulleys with my 50 generator. I have read the long thread form December of 2010 regarding belts, changing pulleys on water pumps etc. Thanks for any help and advise.
