OK guys....I KNOW that I want EFI on my new blazer build, but I'm not sure what route to take. I already have a built 350 in the truck, but it has a Holley carb that keeps flooding out. Should I really fool around with adapting a used TBI/TPI to my motor, or just buy one of the add on kits by Holley or Edelbrock? Which ones is better. Any thoughts? Pros/Cons??
