I have the valley tray and it is a solid (shell) lifter cam. I have four access points to work with.
Pretty sure that PCV entry into intake manifold is going to be the new fitting I installed in the right side of the plenium between the carbs. The front manifold oilfiller tube ,two valvecovers each with a screw in
oil filler - breather hole, and the rear center of the intake manifold base. After the trying to pour Mobile 1 in (the
oil bottle neck is as or larger than the tube and the tube top is much lower than the valvecover). So the front intake manifold filler tube is getting lenghtened to make it as tall as the valvecover. I'm planing on making a new tube from 1 3/8" stainless tubing a few inches taller keeping the internal baffel at same height so a funnel will fitin the tube for actually pouring
oil in the engine and not all over the outside of the valvecover and intake manifold. I plan on making a slight bend or kink to move the breather cap maybe a 1/4" away from the right valvecover. My old tube has some ulgly scratches in it anyway.
I'm Not liking the fresh air coming from inside the aircleaner bases as they are now. As it sets now with a PCV valve in each valvecover, when going full tilt ,they can pull enough flow into top of carbs to make a mess. So to convert those locations to breathers I would probably continue to have a mess. At this time I'm thinking about plugging the holes in the aircleaner bases and getting the fresh crankcase air from a breather (puke) tank with an air filter located on the fender wall or the like . I have an 1/2" alluminum T that I was going use to tie the breather hoses for the two valvecovers from one source out of view in the area under the carbs. I've bought a lot of peices bt knot having the complete plan there is still more to aquire. I'm still listening.
