I wondered how long it would be - not long. 
Now that's a very good point. Here's what will be black:
- Fender liners - to be painted SEM black
- All brackets, like the huge A/C compressor one, the funky one for the P/S pump with the tensioning bolt, alternator bracket, etc
- Bottom of the air cleaner and the dual snorkels plus the cold air ducting
- Radiator
- Radiator shroud - painted SEM black
- HVAC box - painted SEM black
- Blower motor

Don't forget the headers - they conceivably could be done a given color, or maybe you are going to leave them shiny.
Either way, after all that stuff goes on, and the exhaust, I find there isn't a whole lot of the block actually visible from a guy standing up over the fenders.
So I agree with you a bit of blue wouldn't be a bad thing, and even if you did the intake or even valve covers in blue, I doubt it would be overwhelming with all the other aluminum and black going on.

None of the professional powder coating companies I talked to were interested in coating headers. They claim even with the high heat powder it wont stay on there. Then there are the POR 15 products. The web is full of horror stories using that product on headers and exhaust manifolds. A guy would think it would have everything to do with the prep, but I read threads about people who were 8 page micro analysis material and put days of prep into the process and got a couple months of life out of the coating.
When it comes to headers you are either on board to shell out the money for stainless or you should go the Krylon BBQ grill paint route.
Might be another good thread topic Gary. Being that SS will be adding some bling under the hood as well.

Luke - Thanks for reminding me about the headers. I'd forgotten them. As for the blue, I'm going to have to see the covers in them.
Bruno - Couldn't have been an 8-page microanalysis as I've not done one on headers - yet. However, I did read an article in a mag just last week where they tested the same company's headers in various tube sizes as well as with/without coating. The tubing size changed the torque as well as when it comes in, but the coating didn't change the torque at all. However, it made a HUGE difference in temp. The painted tubing ran over 800° while the coated ones ran around 250°. Looks like I'd better go that way if I can.
Jim - Kinda doubting titanium is in Dad's truck's future.

Depending on how the collector is tuned I'd imagine the scavenging is better.
We had some discussion on radiant heat transfer in the other thread.
I guess it doesn't matter much which side is reflective. (towards or away from the source)

Not sure what they were coated with. Will try to find the article and buy the mag.
And, I would doubt soot would reflect at all since it is the perfect black. But, would the inside of the header soot up on a pn engine running well?

Those headers would have had the ceramic coating from HPC, Jet Hot etc. but I'll guarantee you'll baulk at the price.
Unless you need/want the thermal performance, the price jump to stainless headers is much less.
Last time I checked here, the price of the coating was nearly the same as the headers.

I've had two sets of headers ceramic coated by Jet-Hot with their "Extreme 1300 Series" coating. They have several colors to choose from (including blue) or polished. Price difference between these is pretty negligible, about $20-$40, with polished being cheaper.
I just got my 460 headers back from them a few weeks ago. Because they were sort of in rough shape to begin with, I didn't go with polished because it would have shown all the dents and gouges (I bought these headers used, and the previous owner had beat them pretty good). There is a terrible picture below, I chose medium grey. The price was $350 including return shipping.
I also did the headers on my 250 inline six with their polished coating. Looks real nice, and never needs polishing.
More than looks, what I like about this coating is that I pretty much never have to worry about rust, and engine compartment temps are lowered significantly. Over the life of the vehicle, I may well recoup some of the cost of the coating in the decreased wear and tear from heat on engine components and accessories.
They also do their coating right there in your home state, Gary.

Luke - Good info. Thanks! And, those headers came out looking good, that's for sure. Is there a clause that says you can't use them on a new engine for break-in? I've seen that on a lot of headers. Also, did you notice a difference on the six? A temp difference - or anything else for that matter?
And, I wasn't aware they are in OKC. That's cool as I could easily take them down there.
