No PVC, no place to add 3 needed.
I find myself once again turning to the forum folks for answers. Stroker motor 496 BBC Gen 6 version... Carb (4150 style), supplied by TRERacing engines, as are the fabricated valve covers. Using a Victor Jr. intake....
Not one place on the intake, carb or V covers to hook up our 3 vacuum source points needed. PVC needs one, vacuum advance at the distributor needs one and and then the power brakes....
We added a 1 inch spacer to the carb, drilled and tapped for a 3/8" hose barb that got our PVC hose connection a place to plug in carb end -but not sure where on the valve cover on where to drill the hole drivers sid to add the PVC assembly and grommet. We did purchase the Moroso grommit that is supposed to prevent oil being pulled into the PVC valve, but from what we've read it the grommet doesn't work. Just looking at other engine installs they seem to be every where. Our V covers have nothing to act as a chanber, just a blank cover ready ro the grommit to be intealled.
So plan is to locate the hole in the v. cover to a location between the push rods and rockers nnd hope for the best. That still leaves us with the need for two more hose connections for the power brakes ande dist needs. Thought about using a fitting to allow all three needs to be handled with the one spacer plate hole we added with one of those t-type, but not sure that each item need would be answered by this one location. Not to keen on drilling 3 holes in the spacer plate
Sketchy drilling the carb base plate or metering block to add the two still missing vacuum sources.
Any suggestions on the proper way to add the 3 vacuum ports locations we need?
Thanks in advance,
