High Volume Oil Pumps

[AzCoupe]

I'm trying to dig up some high volume oil pumps but have a couple of questions. I need to know the shaft dia and length. Anybody know off hand?

Az,

Can't find my calipers, rough with tape measure 5 1/8 long by 5/16.

Azcoupe,

Well this is disturbing, here you see the one Mike at the bottom describes, same dim at 5/16 (.310) and 5 1/8 (5.125). The top one in the caliper is same dia. and the length is just under 4 3/16 at 4.180. Where did this one come from? If the bottom is the 200's, then the top is out of my old 289 block? O.K. now I'm confused too.

Cheers MIke

Thanks guys, I thought it was 5/16" but wasn't sure about the length.
