I'm at 9 inches Hg, pushing 10 from time to time. This is manifold vacuum from off the conversion plate on a D8 head (200 ci) with an autolite 2100 1.08 carb.
I've got a 264/264-110 degree Hydraulic Cam from Classic Inlines, and am at 6500 feet above sea level.
I know vacuum depends on the cam and elevation above sea level, but was hoping for a bit more vacuum than that to run those vacuum wipers on the early Bronco. How do I test so that I know if I have vacuum leaks? I don't feel like the idle screws are super sensitive to adjustment, but then I've rarely been around a 2 bbl carb, so have no frame of reference.
Would it hurt to put black RTV sealant between the manifold and the conversion plate? I've got a thick cork/rubber gasket in there now and don't know if that material is made for that application.
Thanks...
