Holley XP vs Mighty Demon

I had a Mighty Demon 750 on a 425 rwhp solid cam 440. It was jetted close ootb. Jet up on the secondary and all set. I didn't have to mess with that carb EVER. You can add a bigger carb with an open plenum. And if it's truly street only consider a vacuum secondary carb.My 2 cents....
