Hello all. My truck project was tuned and running when it developed a knock when warmed up. The Gent that rebuild it was in his eighties and three years later his shop won't answer the phone...hopefully he is on a long vacation.To the point.  I did a R&R with a 292 rebuild I later bought, that has a Neilsen  "Hot Street cam and was wondering what I should set the timing. The motor wont start unless its past twelve degrees and max amount of vacuum is 15 at thirty five degrees. The cam is a Nielson Cam, 280M Grind   Adv.Dur. 280    .050"Dur 232    Valve lift 1.43 Ratio .432" Valve Lift 1.54 Ratio .465"Since this is all Greek to me I would appreciate any and all help.
