....IF you have the bosses on the head you will be ahead of the game considering what some folks pay for pulleys ect. I used small block, 305, and used the brackets off the V6 S-10 pickup. Worked like a charm and the a/c pump and alternator are up top for easy access. Just some food for thought.
I got lucky, a friend of mine gave me the brackets and even an alternator for free!! Sometime you get lucky.
