Pretty much all front-sump small blocks use the same pan and pick-up tube. You can even buy them new from Summit or whoever -- like this one:

You'll see on the page the correct pick-up tube for it. You can use the same pump - that is the same.

If you still have that small-block in your garage -- I think it had the correct pan too.
