Try again with pics
Anyone know if these will fit my 75 half c10. They are off a 73 454. Maybe out of a motorhome? They are listed as police package manifolds and are nodular iron. Anouther question- what is the best way to restore these?

Re: Try again with pics
I can't say for sure if they will clear on your application. I can tell you to restore them you can bead (or sand) blast them.
I really like the Eastwood brand Hi-Temp paints. They leave a nice "as cast" finish and can be sprayed or brushed.

Re: Try again with pics
Ceramic coating is much more durable on exhaust manifolds than powdercoating.
Powder coating is baked on at around 450 - 650 degrees and the exhaust manifolds can reach temps of up to 800 degrees and burn the powdercoating right off.

Re: Try again with pics
They have some powder coating that is tolerant up to around 1000 degrees now, but still wouldn't use it on the exhaust manifolds.

Re: Try again with pics
It seems that I read somewhere that big block manifolds (older ones anyway) were all pretty much the same dimensions, except for some higher flowing Corvette manifolds that were totally different and wouldn't fit into other chassis. So if that's true, you should be all set.
Something else that is a little off topic, but if you're going to be removing the air pump tubing you could probably take a die grinder and clean up inside of the manifolds where the tubes come into them. There's probably a little bit of a restriction right there where the tube holes are. I did that on an old Chevelle I used to have.

Re: Try again with pics
I found these advertised on the web for sale and had listed c10 73-87. Do they look the same to you?

Re: Try again with pics
They are high nodular iron thats why they look different from the regular crusty iron. Granted mine need blasting but they have been out in the rain and heat for years and still look relatively good. Im sure they have something sprayed on. Not sure what either. Nodular iron is always the better choice.

Re: Try again with pics
I use POR 15 hi temp exhaust manifold paint. I drive my truck daily and they still look brand new, even after 4 yrs. You can brush it on or spray it on. You can get it in cast iron finish (stock), bright aluminum, or black.
