Well I tried the dipstick vac check with valve covers,dist. vac, carb and manifold ports blocked. I got no vacuum reading and no pressure reading but did start getting some valve cover oil drip though gauge showed no pressure my guess is it was starting to build some. I may just register the car so I can drive it some and see if things get better or worse with after I dial in my distributor. Have you guys used these plates you can get at Mancinni's ? I bought one for my Big Block but currently am happy with how is performing to try it. FBO Mopar Distributor Limiter Plate
