I had a problem of pre-oiling the engine with being back in the firewall. Not impossible but a pain. Bigger problem was, if I pre-oiled it from the normal distributor location, I would have to do it with the entire intake off so I could get at it. Then install the distributor and all of the intake etc., which would take a long time. Since I had the remote oil filter system I simply rolled the little 4 cylinder block in place. Made an oil adapter from an old Pontiac filter adapter with a -12 fitting and hooked the two together. I'll run the oil pump with the drill on the 4 cylinder and pre oil the 406, then I can have it ready to start in minutes after hooking the oil line back in place. The oil will go through the filter and I'll get an oil pressure reading from the filter housing. If I need to run the pre-oiler longer I can let the oil drain from the 406 as I'm oiling it and just add it back to the 4 cylinder.
I also added daylight running lights that double as turn signals. They are on all the time the ignition is on and when I need the turn signal they blink from white to yellow, back and forth.
More stuff done.
