I have a theory for the off center oil passages of the main bearings and it is about oil flow going all the way from the pump to the last rear bearing location. It was creating a restriction so all mains were getting the same amount of oil regardless of the pressure lost across the block. At the end of the day, how many engine builders have noticed an issue with the front main bearing?
One of the most important mods is to restrict the oil flow to the rocker arms so oil won't flood the heads causing Valve cover gasket leaks and starvation of oil back to the oil pan . It's easy to take a 5/16 screw about 1/2 inch long and grind opposite sids slightly and place it in the oil feed in the head to restrict oil flow to the rockers . THE head gasket will keep the restrictor from going into the block and you can retrive the screw with a magnet if you wish .
Also a good idea is to restrict the oil channel in the heads. With holley jets. Because there is so much oil coming up to the rockerarms. This helps to keep more oil down in the engine
These mods make perfect sense to me but I’m wondering what John Kaase or Brent Lykins would say about these mods?? It seems to me that oiling issues seem to go hand in hand with FE’s.
Is there a video of the 1/4" roll pin or push rod tube being installed in a 390 fe cracked oil gallery causing oil in coolant? I'm exhausted trying to locate a video on this topic.
Ive always wondered what the heck the engineers were thinking when the FE was made. I wonder why Ford engineers didn't know how to build a proper liling system. I rebuild A LOT of 5.4 2 and 3 v engines and Ford still has lots of stupid piling problems you need to fix
the OEM's were building stock engines all they needed to accomplish was that it worked good enough for a low rpm stock type engine when mass producing anything the goal is to put out a product that is good enough for the intended purpose with the least amount of production expense possible, so the thinking was it's good enough this type of manufacturing is not unique to ford it's every assembly line product. this leaves room for lots of improvements when doing a custom build
Typical Fe stuff those standard athlete blocks weren't meant to be high performance that's why they made the side Oiler I think they were a great pulling engine I've pulled many loads way too big for a pickup with those old Fe series in the F250s and 350s
@Myvintageiron7512 good information, do you have any ford fe 1960 hi performance heads,small chambers,and do you have any 406 fe heads,or 427 tunnel port,and 427 high riser heads
