I was wondering on the Holley 650s 2X4 set up what jet sizes are being used in the primary and secondary circuits on a 427?

Thanks

This is for my Dad's ERA 427 that he is running 2X4's. I am trying to help him get his running a little better. It appears that it is running way to rich. I thought I would ask around to see how others have theirs set up. I know running two fours will always seem to run rich.

Hardiman,
I have twin 650's on mine with 58's in the front carb and 60's in the rear. I have run 56's in the front carb and 58's in the rear but it runs too lean the 90 degree days.
I also have a somewhat "mild" cam, Comp Cams 270..........
