Reply to "Mechanical vs Vacuum Secondaries"

The sizing calculator and a lot of what I read for a stock 351C street engine with upgraded intake and exhaust says you need no more than 600 cfm.  Gary Hall told me the same thing and sold me my first Holley 600 which it replaced.  If you plan to run wide open, maybe get bigger but the 600 is what it says.  I know the forums all say 850 900 whatever.  As for cranking,  the accelerator pump holds fuel and two pumps and it starts right up.  I have an edelbrock on a 350 Chevy that sits outside.  Cranks for probably 5 to 6 secs and fires.  Filling bowls doesn’t take that long - at least that’s my experience. I remember Gary warning me not to “over carb” the car as all it does is run poorly.  Just sharing what I know from experience.
