Innovators West Big Block Ford Belt Drive w/BBC Crank Snout 5403

Innovators West Big Block Ford belt drives feature a billet machined aluminum cover, anodized precision machined pulleys and a top quality Super Torque belt. This #5303 belt drive is for engines that have a crankshat with a BBC crank snout diameter (still must retain BBF crank key position).

Note: For Big Block Ford applications that have a block without the BBC accessory mount holes, use model #5404. #5404 will allow most any accessory designed to bolt up to a BBC block, to be mounted to the BBF engine. This saves time and money on having to fabricate custom mounts for your oil pump, vacuum pump or other typical front mounted accessory.
