is this a fresh engine that you just built that the machine shop tanked?
what i like to do on fresh builds with a block that got tanked, is to hose it off with brake cleaner after assembly is complete to wash off any oil that's run around onto the outside, then dry it off with paper towels while its still wet.
then paint it directly with eastwoods ceramic engine paint with hardener added.
my engine still looks as good as the day I painted it, and it's now 2 years old with several thousand miles on it

No its something that has been together 6 years. Some of the old paint is stuck on it really good. Brake clean isn't taking it off.
I want it to look good but not looking for a show car. 
Given that, I would degrease then scuff real well with scotchbrite. Then paint

Tape off all of the holes (very well). I'd use an abrassive scotch pad on an air powered angle grinder to scrub every inch of the block of leftover paint, hardened grease, scale, etc. (you can do it with hand held scotch pads as well but it's a TON more work). Then get a gallon of acetone and wash down all of the surfaces wiping after it with a clean white cloth (lintless is best, terry cloth, etc. not reccomended). After you've gone over it several times do it once more for good measure, you want it to the point that the white cloth is still white when you are done.
Once cleaned skip primering it and just spray on a thin coat of single stage enamel, let it dry and follow up with second more moderate coat to cover. You don't want it too thick, just enough for an even full coverage (this will prevent chipping/flaking issues down the road).
I HIGHLY reccomend paint from Frank Badelson (sixpackfrank@aol.com) he sells the same type of paint and colors that the factory used and it holds up EXCELLENT if applied as directed. If you don't have a paint gun you can but a Preval air sprayer for a few bucks and they work great.
I painted this Hemi with it using the directions above back around 1990 or so. This picture was taken in 2008 and I just looked at it again 2 weeks ago, it looks just as nice.

Maybe I am cheap but I plug all holes as others have said. Then I scrap all of the crusty stuff off and give it a good coating of oven cleaner. I let it bake for a couple of hours in the sun then hose it off with water. Then I dry and paint. Oven cleaner is a poor mans hot tank.

This is a good write up , when you say to scrub every inch of leftover paint do you mean to remove it completely ?
As far as the Baldenson paint , he's doing an engine for his race car , I know Mike may be budget limited , that paint probably cost more than he has in the engine

I like this oven cleaner idea , I have a block that was cleaned and machined and the cleaning tanks today are nothing like those of yesterday and it still has most of the old paint on it. The guy I'm doing this for was crying about the paint still being on it and I was trying to figure out a way to get it off ... this may be the trick

It may take two cans of oven cleaner but, it takes the paint off really well. It dose leave the factory painted quality codes or whatever they are though. I have done this many times and the engines look like they came from the machine shop hot tank.

I have a little bit more than that in my engine but its close! 
I had already bought my paint prior to posting this. Its just Dupli-Color Chrysler Blue.
