Depends on the single plane and the displacement. The Holley is a small single plane. We will see and will report my findings this spring.
A tall big single plane would suck for the street I am sure. We will see.
I’ve run a a older Torker on a mildly built 413 and a 440 Super Commando in a 4 speed and no problems. I really think it’s not an issue with a stock performance or better cam vehicle in a RB anyway
