Rebuilt 225 first start

As above with the fuel into the carb bowl.

It can take a loooooong time of cranking on a /6 to see the oil up in the rockers when fully assembled. If you do this, with the rocker shaft off, then I'd be interested to hear how long it takes to see oil up in the feed hole.

BTW, if you used a Moly based cam lube, I would not worry about the oiling. If you did not use a Moly based cam lube, I would be pulling the lifters and generously coat them and as much of the lobes that I could reach with this cam lube. Protection of the lifters and lobes in initial start up is its job. Just saturate the valve/rocker area with oil.

With a points system, disconnect the distributor lead and connect an ohmmeter to ground. You can use that to accurately set the ignition timing before you ever start it, but rotating the engine back and forth across #1 TDC firing point and seeing when the points open while rotating the engine CW through that point.
