New engine prime ?
Wiped a cam in my new 454 last summer. just got done putting in the new cam. I'm using one of the Autozone priming tools and 1/2 drill. I cant get oil flow up the push rods.
I have the oil heated so it is thinnned out
I have rotated the engine in 90 degree increments
I've run the drill for several minutes with no luck
I had good oil pressure (60 psi) when the last cam wiped so the new pump was workin fine.
Nothing changed but the cam
Any ideas what to do or where the problem may be?

I had the wife watch the oil pressure guage with the key on. We're showing 45 psi with drill turning so I know pump is working. Oil is still not flowing to the top end.
I've run the drill for a solid two minutes...does it trake more?

I burned out a 3/8 drill when I primed my engine. Do you have the priming tool that has a big washer to cover the dist hole?
Even with a 1/2" drill it took a while. I never did get any oil out of #1 or #2.

Did you check direction of the drill?

It should have the big washer on top and a piece in the center. This will allow theoil to get up top. Without it you will not get much pressure. I have run my 1/2 drill for a good 5 minutes to get it to all the rockers. Give it time. Let it run.

Yea you need a good priming tool, the one I have is just a shaft extension to turn the pump, pretty much useless because you need one that fits the same size as the distributor to allow oil to flow to the passenger galley

I use a plain old chevy distributor that I cut the top off and removed the cam gear. It fit in the block fine and I turned the shaft down to use a 3/8 drill with it. I also use a mechanical gauge in the block so I can have it in front of me when priming.
Good luck

i welded a bolt to a distributor shaft and used my air ratchet. after about 30 seconds oil was venting out the oil pressure guage tube. i let it run for about 5 minutes and noticed that when i removed the ratchet, the back pressure in the pump would rotate the shaft counter clock wise about a full turn. felt good about that.

That's a fresh idea. Thanks.
