Need some old car pricing help?

[Guest]

Well I thought I had my price list in good order Nope.
No need ceramic added in. I will just have to see what I can get and need in the small quantities when ready I guess?

pricing on old 4 and 6 cyl cast iron header.

Pricing on 4 and 6 flat heads( what powder is best for that ?) Heck I guess the get no hotter than the rest? They don't even have the valves in them.

Are there any extra steps than need to be done on this old stuff so it does right? The 66 water pump I did turned out great with no out gassing problems.

Also from what I have read, it said do the coating first and then machine work after? I guess so all is cleaned up after you blast it all for coating? Just hope the machinist does not screw it up?

The old car industry is accepting the newer things now because of can't get the real stuff any more? About time I would say. They are now more interested in the color being correct than the process that did it but some of them old guys just keep on and on redoing when you could do it one time and done If done right of course.

OK what have I missed???

Duke, I can't help on the ceramic. I was going to suggest one thing on the flat head cylinder covers. Do they have any water passages in them? If not these parts being directly part of the combustion chamber are likely to get much hotter that modern cylinder heads. You might need to go with high temp if they don't have water jackets inside to cool them. I don't know this for a fact just thinking what could or might happen. Maybe someone who has done these will chime in.

I think you are right on no water in the heads. They are not but a few inches thick. They call the flat heads and flat they are for sure I guess the best thing is coat norm below and higher temp on top? I have seen these motors painted but that was before me powder coating. And the one I saw were done in the org color and there are not that many high temp ones out there? Got to go searching some old car restorer forums I guess?

Duke, of all the flat head engines that I have dealt with, they all have water running through the heads. They have to be cooled because of the combustion chamber. That being said, the temps on those would be hotter, but if they don't burn off the paint, I would think powder would be fine. Water temps are the same for flat heads as with any other, 180 degrees average. If it were me, I would just go ahead and powder with regular powder.

As for coating and then having them machine them, I would not do. Have them do machining first then do your coating. Pricing, I would have to think that over a bit. $50 to $75 would be my guess.

Thanks for the pricing. I think now what I remember on the machine work was maybe doing the finish honing after powder coating on the blocks. I guess the heads would be fine to have every thing done and ready to put back together after coating. I know they make a paint for the inside of blocks and heads so that the oil will run back to the pan quicker. Have you used any powder for that? I would think it should be fine as long as every thing is prepared right just like coating any thing else so it stays where its applied.

HAVE A VERY MERRY CHRISTMAS GUYS
