Maybe I should have said the "Y" was Ford's first attempt at buildin an AUTOMOTIVE overhead valve engine.

GAA, GAF, GAN and GAC were all huge military engines, built to government specifications, delivering over 1,000-ft/lbs of torque for aircraft and tanks.

Our '59 Galaxie came with a 292 "Y". This car is full-size with a real frame, four doors and it is heavier than a Squarebird. At under 300 cubes, the engine is smaller than a Mustang engine so the car is underpowered. By comparison, totally unacceptable for use in a Squarebird which is probably why Ford didn't offer it. Instead, Ford spent big money to design, develop, retool and manufacture the FE with mega-changes over the "Y" design.

Hydraulic lifters cannot fit in the "Y" so lash adjustment is forever a part of my tune-ups.



The oiling system is terrible. Without 'oiling modifications' the "Y" will self-destruct due to rocker arms that load up with dirt that chokes off shaft lubrication and the center cam bearing that wears and closes off all oil to the heads. Those same oil ports that feed the rocker shafts go through a 'Z' between the block and head on both sides. The rear seal tends to leak and 'heat issues' are caused by adjacent center exhaust ports in both heads.



The timing chain is only lubricated by blow-by gasses on their way out the draft tube. All that and more was fixed in the new FE design, then the FE underwent further improvements. The "Y" could not be improved so it stayed the same and was allowed to become obsolete.
