On the intake, if you do send it out to have it blasted, please do spend hours cleaning that crap out. One of our own is in the process of replacing his engine due to that stuff getting sucked in to the engine. Old motor is a total loss.
If you are stripping it down yourself, I've found it easier to take a hand held sander to it. Then you only have to worry about getting the grooves by hand. I do that before I even think about sticking it in the blasting cabinet. Huge time saver. Pick up one of those small palm sanders from Sears, they work like a charm.

Just an update on the thread.....I've already had the exterior powder coated. It's the loose stuff on the inside that's been driving me nuts. Not much if any left now. I've got a palm sander......just can't figure out the right angle to get it in those stupid tube things........
Thanks Though!

This is a good thread. I media blasted my intake 2 years ago with heavy glass beads. I first tried chemically stripping the intake. That was a joke. Blasting was the only way I could remove the original coating. Then spent hours in a tub cleaning, re-cleaning and re-cleaning again. No troubles so far. But, I'm curious if these shops are actually using soda to blast the intakes.. We use soda here at our shop, at around 100 psi. Its so fine you could blast one single spot for hours and not touch the factory coating. Are these shops actually using soda? If they are, how much pressure are they using?? If anyone has some experience/knowledge of high pressure soda blasting I would be very interested in hearing. I suspect these shops are not using soda, so please be careful folks.

Was that Blackshark's 81?
Was that BlackShark's 81 or another one in the fleet? 
Rob,
+1 on the lickably clean. Blackshark inadvertantly fed his engine what we believe to be a somewhat small amount of soda blasting media. To say the results were not pretty would be an understatement. The engine ran less than 30 minutes and completely destroyed all the brand new rod bearings, cylinder walls, rings, etc. Basically everything that moves within the engine is now toast. Please clean that intake until everything that comes out is totally clean.

Had my intake blasted with glass... So far have soaked the tubes ('85 US S) in simple green and warm water, scrubbed with bottle brushes, blasted with high pressure water then air, soaked and scrubbed again and water blasted again. This weekend I'll take the whole lot of parts to the car wash and spray with engine degreaser, high pressure blast again, rinse and out-gas in the oven... THEN it should be ready to coat.

FWIW, don't use black slag in your intake. You'll die of old age before you get it all out.

Oh great, another thing to have nightmares about. I must have spent 20 hours scraping my intake and it did not look nearly as good as the intake pictured here.
There was still paint that was who knows how loose on the inside.
