Engine Paint - Assembled or Individual Components

I am getting my engine components back from the machine shop and had a question that may make a good thread.

Should you paint individual components or assemble the engine and then paint? What are the pros and cons? How were they painted from the factory? What specific things, if any, should be masked such as freeze plugs?

I know there is an element of personal preference, but looking for an overall feel from the group.

I painted mine after it was put together minus the carbs, dissy, and pulleys. Also I taped off the intake runners of the heads and painted the intake manifold off the motor so I could paint the lifter valley pan. I then put the intake bolts through a piece of cardboard and painted every thing at the same time.

I am going to paint my motor soon and have painted another motor before for my other car. I always have painted them separate. This way you know when you take it apart if needed there is no paint build up that will flake. I think this would be the preferred way. My 2 cents.

I painted mine once it was assembled, this approach reduced the likelihood that I would scratch something else while assembling + allowed me to paint nuts and bolts in place. I attached a pic, I probably took around 300 photos of my restoration but my favorites are of the engine.

Looks awesome Tony!
I'll be painting mine in a few months and wondered about the same paint procedure?!?
Especially where the intake manifold mounts to heads.
I should have kept them old intake gaskets with tape to act as a template.

I shot mine with it masked and assembled, minus the intake (which I shot separately). I used Eastwood's ceramic 2k paint, mixed and shot through a gun. That would have allowed me to paint the intake bolt heads with a brush afterwards. I didn't actually DO that because I knew I would be removing/installing it several times when I later took it to the dyno, and the paint would get messed up then anyway.

Did you tap your intake on the passenger side for a second sending unit or did they come that way from the factory in '69?
My intake has the flat spot but it isn't drilled and tapped.
I thought about doing it so I could have the idiot light and the mechanical gauge, is that for both or does something else go in that?

Just another way to achieve a gauge and idiot light together and much easier is to get speedhut gauges, Made in Utah, they are pricey...but nothing good is cheap and nothing cheap is good...

Anyway Speedhut let;s you have both and the idiot light is high and low and set by you at the mark, temp, volts etc. so on my temp with my 160 degree thermostat, I set my low idiot light at 140 and my high at 180...

volts I set high at 15.2 and low at 13.8....in between no light..and it is easily changeble by a button....Hookup is very easy, the gauges glow completely in the dark and you can have any custom wording put on the gauge...you can see I choose blue to match the car and had LeMans put on the gauge face...

I like gauges and idiot lights, they warn you if something is amiss...they won't let you forget to look....Vacumn gauge is period not speedhut

just another way to do it...they come in all sizes as well well....
