Hey guys, my 235 is running a mallory fully electronic dist. I bought from Patrick's. I love it, trouble free. I'm installing a new 2 barrel carb. ( Holley-Weber 2 stage) from Langdon's. He insists it will only perform to it's full potential with a vacuum advance dist. Patrick's say this mallory has a"tailored advance curve for superior performance thru out rpm range."Who is right? Opinions? Experience?
