Yea with Glyptal, and that is an enamel based “paint” but it goes on when the engine is clean, and freshly machined. The rattle can paint on oily valve train parts will not stick and likely end up in the pick up screen. Resulting in a thread on FABO titled “where’d my oil pressure go”?Professional race Engines are painted inside on purpose to allow oil to drain quicker back to the pan.

Poor rebuild job as there is still gasket material on the intake side of the cylinder heads, I still say that it's a spray can overallI bought a 340 that has been completely rebuilt but has overspray on cylinder heads will this be ok with break in oil or is this a problem.

I wouldn't run that engine like that, no wayHey J.B.,
I was following your post about overspray on the engine. I tried not to get too caught up in the energy everyone was hammering you about. By the 8th post I assume you may believe your engine is junk.
I’m not sure of your skill level so I will assume you have some engine intelligence.
I am not trying to say you’re not highly skilled. I do not know you at all.
Any how. If you are worried about the over spray… it is not the best practice but will not kill your new engine. Run this engine for a bit and then change the oil. “A bit” meaning like 2-300 miles. Dries paint that becomes oil soaked will get caught by the filter and flush out pretty quickly. Anything else is stuck for good. Professional race Engines are painted inside on purpose to allow oil to drain quicker back to the pan. So dried oil sticks. Loose paint will float. I like the idea of wiping down with a solvent to catch and clean up any loose stuff.
If you are really concerned then find a good engine machine shop in your area and go talk to them. They would possibly take your engine in and take it apart to the level you feel you need reassuring on. Then assemble it with new gaskets if needed, and let you know where you actually stand. It may cost you a few hundred bucks but at least you know positive if the engine is worth what it was said to be. If you are well tested in rebuilding an engine then I suggest you take it apart yourself and double check a few items like the crank and pistons top and cylinder bores.
Trust me when I say… “you will know.”
Good luck and I wish you well.

Depends what he paid for it. I'd roll the dice if the price was right. These things came new with left over casting junk still in the water jackets.I wouldn't run that engine like that, no way
That's a hell of a lot of work to go through AMC just to take a chance of blowing up the whole works.Depends what he paid for it. I'd roll the dice if the price was right. These things came new with left over casting junk still in the water jackets.
The way I see it, he either has to rebuild it now, or if he runs it and it fails he still has to rebuild it.
If he cleans it, rolls the dice and it turns out ok, then the gamble paid off. If it doesn't work out he was gonna be out that money anyways ripping it down and doing it all over again.
Unless there's thousands and thousands tied up in this or it's a numbers matching block, then roll the dice and get the car running and enjoy it
