Thanks guys. I'm working on a '61 235 which I think is mostly stock. The engine was rebuilt when I got it and I don't know about the innards. It must be overbored a bit and probably a bit off the head to clean it up but from the sound I would say the cam is stock or close to stock. The distributer is a nice stock NOS one I got last year.

Since I have 2 carbs would the vacuum be 1/2 what I had before if I pulled off a vacuum plate?
