    I’m adding more, and I had to cut a gap for the dipstick:

    Wont the crank/connecting rods hit that piece ?

    They won’t, the piece is still pretty far below the windage tray. So oil that comes rushing up to meet that wall will splash up into the windage tray and drop back down.

    My friend absolutely f’ed up the welding of that one, so I’ve made something else.

    Notched the left side to clear oil pickup tube:

    That still didn’t fix the clearance issue with the windage tray. The back section had to be cut again and the horizontal center section removed. The vertical section was cut in half and then the remainder was folded down to about a 30* angle. It’s likely that it cleared the windage tray by less than 1/4”.

    Of the three things that could happen when a new baffle is tested from a 0-30 mph start,which are:

    Oil pressure still drops
    Oil pressure holds steady
    Oil pressure increases sharply

    The last and best option occurred, but the valve cover gasket was loose and I had unknowingly just replaced the only breather with an oil cap, so crankcase pressure was high enough to push oil out of the dipstick hole, creating an absolute smoke show for the cars behind us. Whoops

    Currently tightened the valve cover gaskets and reinstalled the breather, to which I will be adding a valve cover PCV and teeing it in the the intake PCV connection at the front of the carb baseplate.

    Waiting on the grommet from TA and the PCV breather from Advance Auto, which I found on Summit. image.jpg

    Real nice work John. The baffle with a center sump is a good idea. Your list should be almost done.

    Also I’m an idiot, I ran the compression tester with the throttle completely closed.

    TrunkMonkey Totally bananas

    What are you doing on the computer? Gitchyer butt out there and do that compression test proper, like.

    Well, to clarify that, I ran the test days ago. I then installed a second pcv valve and routed it into the valve cover. I installed an oil breather, and the combined pcv valves are now creating a vacuum inside the engine. At idle, I cover the hole in the valve cover where the breather would go and feel a light, even faint, suction. When I ran the car up to the top of first gear, it hit me that it has never pulled this hard before. I will check how much oil the pcv goes through in the next 100 miles and verify that everything is ok.

    The engine should be warm as well.

    I hope you don't till have a heat riser valve....horsepower reducer and muffler eater.....looks like it by exhaust condensation....

    I don’t, I have shorty headers and TA downpipes so they are eliminated

    If the weather holds off, I’ll be headed up to Lebanon Valley today to crack the 13s

    I see you've upped your expectations which is as it should be. I'm thinking you should see 13.3 or better(assuming traction and reasonable weather). You certainly have all the equipment for it. Good luck.
