1. Clean an aluminum intake manifold on the car: Aluminum Jelly, elbow grease, and a toothbrush. Try your local hardware store. Be careful about getting this on painted surfaces. Read the label on the container.

2. Remove paint from a manifold on the car: Paint remover. But don't know how you'd scrub the manifold without spattering the remover all over nearby painted surfaces. Don't know how you'd flush the remover off afterwards when it's done its job. Maybe best to take the manifold off the car to do this job.

What's it painted? Orange overspray? That's desireable. You pay extra for that. Silver? I believe some aluminum intake manifolds were painted silver by Chevrolet.

If the manifold is off the car you can glass bead blast it and it come's out looking pretty good. For up keep I use simple green and water. just protect all your electrical connections
Good luck

Default looks like silver spray paint

I didnt know if the aluminum would come back the way it should after being painted. I would take it off the car first. I guess I need to see some other 1967 327-350 intakes to know if it should be painted or not. thanks guys kelly

1966 L79 intake manifolds are cast aluminum...at the Winters foundry,there should be no paint on it.The # for a 66 cast aluminum intake manifold is 3890490.
I currently have a 3844461 as a doorstop if anyone would like to trade for a 3890490.I have a Edelbrock performer RPM on my car presently and would like to get a genuine piece to replace the Edelbrock one with.

I'll try this one as I have done this job several times. It was not done the "correct" way I have since learned but I am pleased with the results.

This is a ...490 intake I picked up on EBay several years ago. It was painted and filthy but very solid with no cracks or helicoils. There was minor corrosion at the T-stat area (quite common) but a thin layer of JB Weld tidied that up.



The grease and filth was removed with spray oven cleaner: five minutes max, scrubbed with a stiff brush and rinsed with water. The red came off with spray paint remover and again rinsed with water. Next I wiped the bare metal clean with lacquer thinner. Finally I painted (thin coats) with VHT Cast Aluminum Engine Paint. The paint was cured in the oven at 200 degrees F for one hour (when the Wife was not home).

Here is the outcome.





The Edelbrock is the result of a leaky Holley last summer. That unit has now been rebuilt by Lars. Here it is on a second ...490 intake in my basement. That intake has been given the same treatment.

Beading or blasting will ruin the original surface finish/texture; only important if you ever plan on having it judged.

Baking Soda blast might be a better alternative...

I have a 63 340 hp that has an aluminum manifold. I would try www.z28camaro.com for your restoration and for exhaust manifolds too!
