I am with Rumblefish. The 750 would be ideal if you take the time to tune it to the engine....although I also agree with the 625 Carter being closer to "your" tune straight out of the box.

If you want bolt-ability go with the 625....if you have the ability to tune the Holley 750, get the Holley and I think it would work well....I prefer Holley's over just about everything else...they are just so darn easy to work on/tune.
