I ran my late 235 with 30-40 PSI and the bypass filter mounted on the intake manifold with the standard oil hoses every day. No leaks - no worries.
Next spring I will put a full-flow 261 into a 47 chevy.
For oil filtering I want to use copper tubing and mount a modern spin-on filter directly on the engine block behind the generator.
Thanks gearhead for the ford-bypass-valve-filter tip.
Anybody knows where the original filter on a 261 1961 was mounted?
