PS pulley alignment problems

[GotBoykins]

While converting to PS, I realized that neither pulley I have will work. So which crank pulley do I need. If someone has a pic, or the pulley I need, please post up. Here are the pics of my problem, shallow and deep pulley.

Also, would the brackets make any difference? I have two sets of those also, both of them different. One is cast, and one is stamped, all help is greatly appreciated.

Thanks, glad to know I am not the only one.

There are several different styles of pumps. The pump you have is an early style with the bolt on pulley. Those are typically used with the short water pump. What year is your engine, better yet which water pump are you running (short or long)? If you're trying to use an early pump with a long water pump it won't work.

Im using a short pump, the ps setup is off of a 69-72 truck. Im gathering that I need a different crank pulley. The pics I posted are with two different PS pulleys installed.

So your water pump just about touches the timing cover on the rear side?

Yes, very very close.

Well then, i'm pretty sure you need the cast iron bracket and a different pulley to make it work.
