Intake manifold restoration
 

BBC factory aluminum intake manifold. I would like to get it close to factory appearance. Who and how does it happen? Thanks.

Vapour blasting, check motorcycle repair shops in your area, they use Vapor Blasting or also known as Vapor Honing. If all you need is a cleanup the later will work. If you need repaid then maybe CHP.

The above, Camaro High Performance. 👍

Dave Beem is also doing vapor blasting. Dave is a site sponsor in addition to a Camaro enthusiast.

Thank you all for the responses

Every time I click on CHP, my firewall blocker blocks his site. You guys have the same problem?

No

Yep. Tagged as phishing and fraud.

This is what I see....

Here's a link to Dave Beem's samples of restored intakes. He does exhaust manifolds and transmission cases as well.

Rob Walden (at Lamar Walden Motorsports in GA) does fantastic restoration of cast aluminum parts. He can also repair any defect with no signs it was ever touched. Resurfaces all the machined areas as well, if you want.

When you get it back you'll think its a little too shiny, but after it heat cycles on the engine a few times it is exactly what you want!

Need to visit the closest workshop

Steel/shot blast in a machine with "clean" media that is only used on aluminum......

Is the steel shot finer material than the glass beads ?

If your asking me, I dont know the answer...but guessing that glass can be much smaller finer...........however the metal fine Ive seen recently is VERY Small...........Didnt see the
bag to give you a grit size ???

No not finer but it is small. The shot closes the pores of the aluminum and makes finger print proof and easy to clean.

Below are new pics of a LT1 Aluminum Intake # 3972110 1970 Camaro/Corvette

Was Shot Blasted, Shot Peened for 10 minutes in Rotating Drum Style Machine
I wired the intake to the rotating cage so it wouldnt bang against the HARD Steel (cage)
and get dinged/damaged

I believe that this was similar to how foundries cleaned new sand casted manifolds coming out out of molds

I may apply CLEAR MATTE CERAKOTE to preserve the porous surface from Staining...................
