P/S help

[70stroker]

Alright guys the truck im working on is a 70, but i need you square body guys help.

the truck has a 454 bbc, the p/s pump im using is a 75-78 truck pump and resivoir. I had this pump on my small block a few years back. I just now bought my bbc bracket and with the pulley i was using with my small block all the way pressed on it is still shy of about 1/4 inch of were it needs to be.

can anyone tell me what pulley i need. its a 454 with a 76 pump and a long water pump. thanks

I was thinking that the pulley should be the same between bbc and sbc. The only difference should be that the PS pump bracket would be different between long and short water pump. Do you have pictures?
