I have a 396 Chevy engine I am installing in my 65 Vette. The engine is rebuilt, mostly a stock 325 HP engine. Edelbrock intake and carb, oval port head engine. The distributor I was going to use is a 1962 Corvette dual point mechanical only advance. I have to run a Corvette distributor in order to utilize the cable driven tachometer. The engine was assembled several years ago and I can't find the cam card so I am not sure what the specs are. I remember its a Comp Cam hydraulic and not very radical. Question: This is my first BBC engine and I wonder if a distributor with no vacuum advance would be good with this engine for street use. The only other mechanical only distributor I had dealings with before was a 427 Ford and it was fine with no vacuum advance.
