Holley or Demon

Well I was talking to a guy and he wants to trade one of his carbs for some parts I have. I'm just trying to figure out which one I should go after. He said he has the following:
650 or 750 holley dp, choke horn milled off (he said it needed a kit or something, probably a rebuild?)

850 holley dp

850 dp demon that was used for only the break in period. (seems like BG's are a love/hate thing?)

I could use the 650/750 on the small block, or maybe the 850 on my big block then swap my current 750 onto the small block. Right now my 460 has a 750 holley vac secondaries with one metering block. The cam isn't really big, .554 lift, 230@.050, worked over D0VE-C's, lower compression and dual plane manifold.

BG is no longer in business if that affects your decision?

Didn't holley recently buy the company?

BG stuff is being built by Holley now.

Not sure when the guy bought it. It's probably an older BG one. But either way, would 850 be a bit big for my setup? I mean, I have a 750, both small blocks we have can take a 750 The big thing to me is it being a double pumper, so I should get some response out of it. As it stands I know I have to tune what I have because it seems to stumble. It's straight out of the box right now.

I also currently have straight leg boosters as well.

An 850 will work fine on a 460.

I'm thinking, once I tune the 750 I have now, even though its not a double pumper. I should be able to make the throttle snappy. Change the jets, pump cam, squirter nozzel and secondary springs. I'm hoping to make it have great throttle response.
