Breathers on SBC

[Specs]

I recently purchased a rebuilt 1978 small block Chevy motor. I wish to use old style non vented Corvette aluminum valve covers with an old style breather/oil filler tube inserted in an Edelbrock Performer four barrel manifold (Edelbrock P/N EDE-2101) The EDE-2102 manifold has a punch out to accomidate the breather/oil filler tube. I do not wish to run a PVC valve type breather since I do not want to punch a hole or holes in the Corvette valve covers.

Since the valve covers are not vented and there is no accomidation on this year Chevy block to install a "road tube" (rear breather vent tube) will the single front breather tube be enough to vent the crankcase?. I do not what exceessive amounts of oil dripping on my new rebuilt and repainted engine.

for street use, that should work fine specs, with a new rebuilt motor. all you need is a out let for any blow-by your rings might have. if it didnt work you could drill a hole in the lower part of the filler tube and put a pcv valve in in it and run a vac. hose from the carb. like you would to the valve cover.
