Bigger issue is the 0" vacuum at idle and the puffing out the breathers. That cam is not that big and should pull around 6" at least at a 850 rpm idle. I would fix that up before I spend $600 on a converter. Make sure your balancer is at 0 at TDC. Then add the timing tape, set initial at 18 to 20 degrees then make sure your primary throttle blades are not open to far allowing fuel to dribble out of the boosters at idle
