I'm using the Wieand aluminum pump. The only thing with that pump is it that you need to drill the bypass hole into it.
It's a simple thing to do with a 1/4" drill bit using the gasket as a pattern.
A few have used the Edelbrock aluminum pump since it comes with the bypass already drilled.
If you can find one, there is a Ford D0ZX aluminum pump housing made and sold under the old Ford Muscle Parts program.
With this pump you need to install a cut down pump impeller from a Boss 302.
I've been looking for one of these for 30 years and still have never seen one for sale.
