Crank and water pump pulleys

[cmayna]

This might be Cleveland sensitive being a 4 bolter. Don't know.

For a power steering setup without AC, is the crank 4 bolt pulley, a 2 groover with the two grooves next to each other? I have seen some on ebay which the larger groove is around 8" diameter and smaller groove is infact right behind it and is around 6-3/4" dia.

I found the following one [in pic] in my boxes of parts. The larger groove is 6-5/8" diameter and the smaller one is 5-7/8". Total Width is approx 2-1/4". What the heck is this pulley for? Hmmmmm....Alt and smog only?

Regarding water pump pulley, what is the typical diameter and is it a 2 groover?
The water pump pulley I have is 6 1/2" diameter, which would be too big if I used a 8" crank pulley. They'd hit each other.

Thanks

'70/later 351w engines had 4 bolt crank pulleys as well. I never saw one that looks like the one in your picture, though.

Me? I'd just order aluminum pulleys for your engine from either March or Ford Racing (can probably get them both through Summit ... I know you can get the March pulleys through them).

They'll look better and will never break.

John,
I think you're right....shhhhhh!!! Don't tell anyone!! March's 1667 looks like the ticket since The lower rad hose will be on the driver's side.

What are the numbers on that pulley in the picture Craig?
