most people don't seem to grasp the fact that's it's easier to feed two carburetors being you have twice the needle/seat area. there are plenty of electric pumps on the market that will do the job unless you're insisting on a mechanical pump for some reason. 
Yep, I read an article in ND many years ago where WJ stated that very same concept and in fact said he used two Holley standard non return regulators because they fit his requirements at the time.

I think what they are saying is a mechanical pump that bolts to the block isnt going to supply enough fuel for 2 carbs.

Not looking to go with an electric pump, just a good mechanical that bolts in the stock location on a 440. I saw the clay smith pumps just haven't heard much about them.
I heard pretty good stuff about that pump

Can you put one on the other side too? 
I honestly don't know but I think you are asking a lot of a single feed single outlet mechanical pump.

After I bought the pump I found out the solid street roller cam I orderd did not have an eccentric ground into it.

A racepumps piston pump is good to 2000 horsepower, do you think you are going to make more than that? Tim
So they say. That said I have one and it seems to work well. They do not seem to like sucking fuel from a stock pickup (from my internet research). They work great with a sumped tank/fuel cell though. One major drawback is that they are expensive!
