Here is my 341ci Y-Block Ford running on a stand with an open valve cover to show that pressurizing the rocker shafts will not pool large amounts of oil in the head and flood the valve guides. This is not to show that using the overflow tubes is a bad thing, I just want to show that pressurizing is OK.

  • my 292 only wishes it could get that much oil to the top end... When I got my truck it hadnt run since 96' so I drained what oil was in it, and put in new oil. When I pulled off the valve covers to adjust the rockers it was almost completly dry even after running so I ran a couple quarts of atf in the oil for a few hours and it cleaned everything up and it gets more up there but not as much as id like. How did you do that?

    Look at my other videos, I have one that runs through the rocker rebuild process.

  • Wow! Finally, we're getting all of the bugs worked out of the old Y-block after being ignored for years. And see? It's not such a bad engine afterall!

    Now, if someone could import some of those Argentine L II heads and intakes... Or, someone could reproduce them in aluminum. That would be nice. But is there enough interest in such products?

  • You would also need a cam to go with those heads, from what I've been told Argentina has real tight restrictions on what comes into and what leaves the country. But you can still dream ;-)

  • i have a 272 that runs god but the valvtrain wiped right out of it... i ran an old oiler kit that pluggs into the rear of the rails. it worked good till the pass side got pinchd off. i replaced the small copper line with 1/4" fuel injection hose but drilled the valve covers and ran into the over flow tubes.this thing will fill the valve cover right up now and the smoke is insane... i have to figure out a happy medium

  • First off...that thing sounds wicked...second that was way cool running a Y block at 4K on a stand...wow

  • I've done the same with mine when I rebuilt it my just pinching down the overflow tubes. I gained about 10-12 lbs. of pressure and never had any problems with this. Michael

  • Cool video!

  • That was VERY cool!
