Dear Mr Hoyt;
Don't believe it! There's a big difference.
The early engines (pre 54) had 'low oil pressure' systems, running 15# normal pressure. Later (54-62) they ran double that and more in some conditions.
The filter options on trucks with the 261 had the filters mounted on the firewall using 1/2" lines. This is how the factory did it. Passenger cars had the same as pre 54 until 1963 when the filters were mounted on the right side away from the hot exhaust.
I am told that 4X4 vehicles with the 261 engine were mounted on the manifold from the factory but this was an "option" or 'special order' etc.
Back in 'those days' commercial oils had not been developed yet and 'full flow' filters were new too, with Ford V-8 engines having some of the first in 1953.
Today; It's a totally different ball game.
Commercial oils keep their detergent active for about 4000 miles. Changing oil then negates the need for a filter in non-commercial usage.
The "don't sweat it" attitude toward fire safty is foolish advice.
High power magnets on the bottom of the pan work well except with 4X4s.
Good luck.
