OK, one more time- - - - -The original bypass filter canister has a 1/16" hole drilled in the standpipe that controls oil flow through the filter. Whether the original style 1/4" diameter rubber lines are used, or 1/4" or 3/16" OD steel tubing is bent to fit, the adapter for the spin-on filter MUST have a similar restriction built in to prevent excessive oil being bypassed back to the crankcase and loss of oil pressure to the engine. Pick one of the adapter fittings that are used to reduce the pipe threads in the spin on filter mount, and drill and tap a 1/4"-28 thread into its inside diameter. Then screw the Holley jet into it. You now have a restricted fitting to control oil flow and prevent the engine from getting starved for oil. It's really not as mind-boggling as it seems- - - -simple drilling and tapping! I use Holley jets because I have several dozen of them left over from my round track racing days. The thread isn't exactly 1/4-28, but it's close enough for a one-time installation.
Edit: I will probably have to do a photo shoot to show the step-by-step procedure for making a restricted fitting. Then only willfully obtuse people will have a hard time grasping the concept.
