OK, I just checked that cam out. It's 250 degrees of intake duration at .050 lift. You'll be lucky to see 4 to 5" of vacuum. You better be good with carb tuning and scratch using a Edelbrock, AFB or Thermoquad.
Sorry I missed this one early when I was going through before. Your right you should have seen me banging my head off the garage wall the first times with an edey carb. The guy who is going to go through my engine for me runs his car off the money he makes tuning other guys cars, in fact he sold me the carb I have for it now for $100.00 and that included the rebuild and tuning it. He said something was wrong with the motor last year I just didn't want to listen.
