I picked up a 59 ford panel with a 69 351 w in it. It appears to be stock 2v engine....the problem I have is the timing and vacuum advance. It's set a 8 bdc and it jumps to @ 50 at about 1800 Rpms w vacuumed.... Stays at 30ish unplugged.... How do I resolve this?? Posted using the Full Custom H.A.M.B. App!
