bracket for a 351 ford engine using the P600B

Simple question:
I have a 5.0 H.O engine using the p600b.
Now I want to swap the engine for a 351w, and I want to keep the p600b, but I dont now a couple of things:
a) Can I use the same bracket?
b) Can I use the same crankshaft pulley?
Someone with any ideas?
Thanks.

Depending on the year. I had a 94 cobra and I used the stock brackets and I thought i heard from procharger that the old brackets would work.

Everything should stay the same, except for the belt length.
