All Plugs Fouling on Right Bank

Your timing cannot be set with vacuum on the can. It must be removed. It should be around 34-36 total by around 2500 or so. Then the vacuum can needs to be hooked to a ported vacuum source.

But total on a street car is not terribly important. You need to have around 20 degrees initial and 14-16 mechanical. This is without the vacuum can hooked up. Once you get the initial and total right, hook the vacuum can to ported vacuum and you're done.
