B4 water pump on “A” OHV conversion
 

We have a new leakless B4 water pump , is it possible to fit to a miller OHV head that is designed for the 4 bolt model A water pump?

I don't think so. The B pump has 3 mounting bolts, the Miller has 4 and would accept the A pump but should have the Miller pump which is like the A but has an air-bleed hole at the top. By the time you put an adapter from 3 bolt to 4 bolt the pulleys wouldn't line up, HOWEVER, if you have the '33-'34 B pump which is shorter, an adapter could possibly be made to work???

Thanks Jim that mirrored my thoughts on pulley placement. So simple answer is , spend more money!!

That's it! They are available thru millerhi-speedheads.com

RE;the Miller has 4 and would accept the A pump

See my first link, the 4 holes are not the same as Model A so you couldn't bolt an A pump up anyway.

Yes thanks for that redmodelt I did see your link and till then did not know std A and OHV pumps were not interchangeable.

Neither did I, but I'm not a Cragar-guy, I like my 4-port Riley's!
