Reply to "EFI versus Carby"

The Pertronix high energy multi-spark system improves idle.

With a Holley 750 cfm carburetor with mechanical secondary and double pumps I had a stable idle with an AFR of 15.5, so "lean" that does not foul the spark plugs. The vacuum at 900 rpm was however only 11 in Hg with my hydraulic roller camshaft of 231° at 0.05''.
With the new camshaft of 235° at 0.05'' and the new distributor I have not yet refined the settings and I cannot say what it will be.
