Well I guess I have finally determined this engine to be a 55 or 56. In 57 Ford went to a spin on oil filter eliminating the old 90 degree housing and cannister filter. Well now....not quite right truck engines had them up to 1964. So I have a 55 thru 57 truck engine. All info says ECG engines were made 55 to 57 in Cleveland and used in cars and trucks. OK Terry, you have a 272 truck engine. Finally found one man here in Wis. that knew what gasket I am looking for, and older fellow and lifetime engine bullder. Yep he said I know exactly what gasket you're looking for. They came with the engine gasket rebuild kit,54,55, 56. I'll call my contacts where I always go to for the hard to find stuff. If I don't call you back in 30 minutes it isn't to be found. That was 3PM yesterday and it now 9:22AM a day later. ZIP He told me that to use just a regular round gasket without the crossbar in it would hamper the filtering of all the oil, probably let some of bypass and not do the right cleaning job.
Also found out that possibly the spin-on kit for a Ford 300 6cyl may have the same block threading and wilth a short filter all would be good in Y-block land. Will find out in the near future. Any y-blockers out there have any experience with this? Just another day in paradise. Tnx Terry
