Ran into the same problem years ago. Had stock 454 steel pullies machined to fit correct and accept blower pulley

That should be exactly what he needs.

We'll probably I can, it looks correct? How much $$$ . I'm also looking for a flame arrester for 850 holley that breathes! This motor had stock arrester on it if you have anything kickin around.
Thanks again Marc and everybody that helped
Dave

How does $100 including the ride sound?
Sorry, no flame arresters left :(

the ones I've seen and used all were 2 piece with a GM pulley for the V belts, now if used for a while they can be stuck together tight as hell..

Hey Marc, I'm sorry I never got back to you on the crank pulley, family member in hospital put the boat on back burner, I still really need that pulley if you still have it? [email protected] is my email also
Thanks again
Dave
