Jaybar, the Holley 950 HP has better throttle response than the 850 as well, and of course goes farther on the top end too. This is because the 950 has 750 venturis, but with radiused entry.

Proform makes a nice 950 HP type carb for around $550, with billet metering blocks, base plate, adustable bleeds and vacuum ports.
