I spun a bearing in my daily driver and I am considering buying my buddies 302 GMC engine.

Do pulleys and generator brackets swap from 235 chevy to GMC?

Will a Chevy PG bolt to a GMC V6. Only if you have the factory GMC components to do so. A PG was an option on 63-66 GMC V6's.

Or you would need an after market adapter kit.

Oops, missed the I6 part. The cast iron PG may bolt up. But a later '63 and up PG will need an adapter. Iirc prior to '63 there were separate I6 & V8 bellhousing patterns.
