You'd need 500ci to see 12 in/hg with that cam. |

You can try advancing the timing to see if that helps. You could also advance the cam a couple or four degrees. But it's going to be hard to overcome that 108 degree LSA by crutching it. Vacuum reserve cans do work...for one or two brake applications. If you have vacuum-assisted brakes you really need to look at an electric vacuum pump made by SSBC and offered through them or Summit.
And just fyi...many of the early 60s factory performance era engines that had beefy cams didn't use vacuum advance distributors. |
