In the meantime, here are my two offerings: First the Transcontinental Alfetta GTV 2000 after the engine rebuild. Did this in crinkle black powder coating on cam cover and altered airbox.
Second it the first spin on the Duetto rebuild, with the 1750cc engine as purchased. I polished up the parts, and the look seems nice, but boring in the white bay.

Michael,
Nice photos.
It's just my opinion but... I think in darker coloured engine bays the all aluminium/polished look works really well and in lighter colours painting or powder coating the cam cover brings the engine 'out' more effectivly. You've got your engines the wrong way around... It's not a criticism though; both of them look great.

I believe you have presented an interesting concept. The Alfetta is what it is, but for the Duetto, I am leaning towards the color route.
What do the purists have to say about this? Red crinkle coat on the airbox and cam cover would really work well with the red interior!
And what do I do with the air filter cansister? Currently powder coated nice black.

THe thin though, that i have notices with the smoothing finishes is that they sure are alot easier to cleand and keep clean! THose crinkle surfaces are cool but can be a bear to wipe clean.

Sorry, but I beg to differ. The wrinkle finish on my cam cover looks as good as it did when first installed five or six years ago. I don't do anything to it except wipe it off once or twice a year, and I drive the car as often as I can (New Page 1)

THis is good news to me then... as i have considered it. But how do you "just wipe it off" when the rag gets caght on the flat (flat as in opposit of glossy) texture and there are all the thousands of tiny crevises in the "wrinlkes" for dirt or dust to be trapped. It must be worse than trying to wipe a wall clean that is textured with a Flat finish paint.?.?

Greetings:
A few thoughts about the wrinkle route. Engine covers have long sported wrinkle finishes from the factory. As Sprintn notes, it would be more difficult to "wipe off", but there are mitigating benefits. Because it is by nature low gloss, much of what might be visible on a high gloss smooth surface will simply not make its presence obvious. Secondly, today's powder coated wrinkles are certainly far harder and more durable than those of old, so they should hold up to a good scrubbing now and then.
Left to nature, a raw aluminum casting will eventually get dingy, and if paint is applied, it may craze, peel or discolor. That said, have been told that some of today's high-tech aluminum finishes are heat tolerant and hold up well.

Crinkle / wrinkle again.
A few more thoughts. Most of the early Ferrari V12's I've on have crinkle finish on the valve and cam covers. My Ausca Alfa spider has had a crinkle black valve cover and crinkle red front cover for more than 40 years. The early crinkle finish was paint. There is a learning curve to get a nice even application with nice even wrinkles over the entire piece  . Over time, with heat and engine cleaners it cracks and flakes and looks terrible  . Properly applied, and cleaned, it looks great for many years and miles  .
Now the GOOD news. It is now available as a powder coat finish  ! This requires the skill and equipment of a powder coat specialist. This finish is a very plastic / flexible. No cracking or drying out from heat. I have just finished a pair of Ferrari ignition wire tubes (one of the first areas to crack and flake on Ferrari's) and it looks great. It matches the crinkle painted valve covers very closely. I also have done Alfa valve covers, and by mistake, an old 101 water pump body. The powder coat crinkle / wrinkle is a finer texture than the paint, in both red and black. It is, therefore, easier to clean.
Now the BAD. The powder coat crinkle is very difficult to remove using conventional methods  . The paint, on the other hand, comes right off with paint stripper. The Powder coat on the water pump body required an aircraft Emron type (epoxy) stripper and even that turned it to a sticky plastic goop  . Glass beading did eventually get it all off, but it took forever. This stuff is durable plus!
Application notes. For DIY with paint, Practice, practice, practice. Paint over a very clean glass beaded surface. If you mess it up, it does come off. For powder coat, you need either proper equipment and experience, or, send it to a professional. It is not as expensive as you would think.
Which do I prefer and use? Both. 'Nuff said.

My cam cover was professionally powder coated. I don't know the cost because it was a freebie from a supplier to our bidness. The cover wipes clean with a cloth or paper towel. I've also used a spray-on engine cleaner called Black Magic 2-in-1 Engine Shine. That was only needed after the 0170 cap rattled off and drenched the engine compartment and again when the Fram oil filter split at the base and lubricated the entire engine bay.

Photos of a V8 engine project some years ago. An engine adapted for the transaxle. Not often seen here I suppose, from my GTV8 project.
Used black crimp paint on the magnesium covers, but I guess this is outdated now
For the GTV8 fans

Greetings Gabor: with photos like these, you will have even more GTV8 fans! And just how did you manage to stick those two blocks together? With epoxy?

So you are transplanting a Montreal V8 into a GTV6? Amazing!

A little less powerful....
Unrestored engine bay on my '70 1600 S
The only things changed are fuel pump and hoses, battery, and maybe the brake booster long ago.

Michael,
Red for the cam cover would be cool, but if you do the filter canister as well it may be a bit too much. Therefore maybe black crinkle cam cover with the 'Alfa Romeo' script in red, and the filter canister in red also.
I have a '75 Alfetta GT in Le Mans blue so I'm considering the polished route. This thread has some great photos which is giving me some ideas for alternatives though. Lots of work to do before I get to that though.

 Nothing special- just a stock 1600 with a little polishing here and there....still sounds sweet though!

Looks good Dan, I like the insulating rubber you have on the hood.
