It'll work good for you as it is the largest CFM oe AFB & is listed as iirc 750 cfm but is nowhere close to that but do check the play in the primary throttle shaft as it's 40 + yrs old & no telling how many miles it has seen. NAPA kits are reportedly a slight better than most though none are worth writing home about and w 99% of oe AFB's having 2 step rods/matching jets, an eddy strip kit will work if you want to play (a few motorhome AFB's had 3 step (AVS type) rods/jets) w the domed cap). I have a NAPA AVS kit ordered and it is $28.09 and you can tap the boss on the other side to make it a dual feed and there was a thread yesterday about subbing in an eddy? viton accelerator pump for the oe leather so I'd look that thread up & order one
