Initial start up

[cst350]

Went to fire my small block up today after a rebuild. The motor sat a while so I put some oil in the spark plug holes and turned it a few rotations. Also pre oiled with a drill through the distributor drive until I had oil coming through the push rods. Motor fired up and ran nicely for a minute or so and then lugged out. I pulled the spark plugs and they had oil on the tips. Think I over did the oil in the cylinders?

I was going to clean the plugs off and try again... any other suggestions?

Thanks,
