Talked with my mechanic last night. Seems the secondaries haven't been opening on the 650 Holley. Don't know how long it's been like that but a few years back I tried to figure the correct prop pitch and the numbers didn't make sense. :facepalm: What kind of performance differences might i be seeing with a correctly operating 4 bbl?
