Holley's science vs Edelbrock simplicity?

Well sure they are because Holley changed over the years while Carter went out of biz. Carter had only one race carb, 4 models of the TQ. And that’s before they were put on production vehicles. They also had an aftermarket TQ suited for Chevy or Chrysler, egr and non egr versions.
That’s it.

Holley on the other hand started in with there racing efforts and never stopped. The OEM Holley is the only comparable model to the Carters.
