That "computer thingy" is the Duraspark II ignition module and it just fires the spark plugs. It performs the same function that the HEI ignition module does but gets better airflow since it is not stuffed inside a distributor cap.

When I removed the smog junk, all the wires in the smog junk went to that box. I dont understand how I am supposed to sell all the smog junk to someone who needs it, while retaining the yellow grommited pooter thingy. The pooter should go to whoever needs all that stuff, including the dizzy.

I understand that an HEI has a module inside the cap, but GM had used HEI for many years, I have too, and have never had any overheating issues.

So, left with no pooter, and no dizzy, I went with what is familiar and easy. HEI drops in, and goes. All I have to do is run a switched 12v with enough current. Thus the relay harness pulling directly from the battery.

Fits. But, not sure how you put a starter back in it. You have to remove starter to get it in. Hmmmmm, no room to re-install starter. Heck, its a four speed I'll just push start it!!! Maybe Gary can engineer a pull starter for it. Sit in the cab and pull it. Lol.

Nice looking, but could you push-start it?

And a PMGR starter is much smaller.

Surely you knew I was joking.

Anywho, the trick to getting the starter and header installed is to take the starter completely out. Drop in header and let it just rest on the frame. Finagle the starter into place, hold your mouth right, say three hail marrys, and kiss your sister.....itll all go together.

And now take it all back apart to start prep for engine painting and oil pan removal.

Re: Little Blue 82

I will be fitting the cherry picker to the engine, removing motor mounts, removing pan, and painting block in place. Im working on gravel....so I wont be able to just go ahead and pull engine for paint. If I could role the engine hoist, Id pull it and paint it.

Still needs some grease and gunk removal. Going to spend the rest of the week detailing the engine and tins.

Going to go with the factory gray. I think I have enough blue on the truck.

The header comes with cheap rattle can paint to prevent rust. I will take the propane torch and cook it off. Hand sand and apply high temp coating. Black? I think so...what do you think?

For looks black is good. But, not so for the life of the starter nor economy. Black radiates heat well, so the starter will be baked. And, the removed energy reduces the flow and, therefore, the power and economy. White is the better choice for that. Or silver.

Re: Little Blue 82

Black does not reflect sunlight, thats why its always hotter. Ive never heard someone tell me a certain color radiates better than another. How does color have any affect on the surface temp of an exhaust tube? Not saying you are wrong, but please do explain how color affect heat radiation.

As far as the starter goes, I thought I might wrap it, or wrap the header. I dont know yet.

Re: Little Blue 82

Remember that my degrees are in math and physics. But, it gets into what is called "black body radiation". Here's the Wikipedia writeup, but the basics are that just as a black surface absorbs more radiation than a white surface, it also radiates more heat than a white surface.

The descriptive explanation is:

All normal (baryonic) matter emits electromagnetic radiation when it has a temperature above absolute zero. The radiation represents a conversion of a body's internal energy into electromagnetic energy, and is therefore called thermal radiation. It is a spontaneous process of radiative distribution of entropy.

So a black exhaust system will radiate more heat than a white or silver one.

I wouldn't wrap headers, of course it's personal preference, but it's the corrosion that I don't like. I would shield the starter.

I first heard about the corrosion from some guys who put it on their dual purpose motorcycles.

I agree, grumpin. Wrapping works until the corrosion kills the pipes.

And any paint is only temporary, so the discussion about color isn't a big deal. However, ceramic coating does last.

Gary, interesting. I would like to see an expirement with a black, white and silver stripe on an exhaust tube. Using a laser temp thermometer, and read the temperature differential of all three sections at the same time.

The stripes would have to be parallel to the flow of exhaust, not perpendicular. That way all 3 colors are the same distance from the combustion chamber.

I thought the absorbsion of radiation had more to do with light spectrum reflection and pigmentation of the surface.

Anyway, I bet if we did find a difference in temps, it would not amount to enough difference on an old ford truck to make any difference in performance or efficiency. I mean, there are so many factors that play bigger roles.

I love how detailed you are Gary. You are a sniper, and I am the guy trying to spray and pray. One day, when I am retired, maybe I can afford the time to be as detailed as you. Cant wait to see your dads truck. Hopefully the end of next month I will be in town. Maybe see you then.

Yes, I too had considered this. I wrapped a set of headers on a 70 chevelle. Never drove it in the rain. Headers didnt corrode. I think if you go mudding, or drive it in rain, or let it sit with the wrap being wet, of course its going to corrode faster.

If heating the intake is as important as everyone says it is, maybe wrapping the header isnt such a good idea. Sounds like I should shield the starter and see what happens.

Thanks for the suggestion.

Sure is! Cylinder #3 tube is what confuses me. Why it has to come so far out, then back down...

I was thinking maybe the tubes are equal lengths, but sitting here looking at them, no way are they all equal lengths.

I dont know. It looks cool. Thats all that matters to me.

Re: Little Blue 82

Not much has happened to blue 82 the last few days. Between work, recieving our chicks, and yard chores, I just havent had time.

What paint should I buy for the engine? I want to go gray. Ive looked at rattle cans, tractor enamel and hardener....any other suggestions?

Not taking the engine out, it may be easier and much less mess to brush on tractor paint. No overspray. The H.A.M.B website suggests using it, and not to worry. They say it will stick and look good as long as you prep well.

Im not going for show truck. Just a nice looker.

The Dupli-Color rattle cans come in the Ford engine colors and work well. My 302 was done in the darker blue and it looks good.

HAMB's recommendations are usually good. But I've not used any tractor paint so can't comment.

I have, however, like Cory used Dupli-Color and it worked well.
