Now that I have determined my Holley is an original Racing Beat modified 465. I'm trying to figure out exactly what Racing Beat has done to make it a "Racing Beat" Holley. Almost nothing has turned up after plenty of searching.

Main reason being, I need to then learn how to modify it for blow through. Which there is plenty of information on how to do this. But i'm unsure if the RB updates will be affected... Anyone have experience with this?
