Gonna need a Holley (or Holley type) carburetor, and patience to tune it

Innnnnncorrect! All so very very wrong!

Any carb will need the time to be tuned and he doesn't "need" a Holley or Holley type carb. He needs the knowledge, skill and time to tune any carb that goes on top. Be it a Holley, Edelbrock, whatever aftermarket carb OR a OE carb.
