Help me pick a carb!`

Well went with this one....Quick Fuel 750 Slayer! So far real nice! Nice improvement over the 625cfm Street Demon. Easy to get into sharp tune as well. Idle mixture/secondary etc. more vacuum too than with the Demon, not that it really matters to me. Pretty happy overall. Still would love to try a mech secondary like a Holley 650 DP for comparisons sake but overall the Quick Fuel is a real nice piece for the price! I upgraded the fuel line etc too. Rubber hose is temporary just to get it running..gonna go all AN hose and fittings eventually.
