Greg,

DO NOT wrap your headers as this will draw moisture when cooling  and hold the moisture until the engine is started and cooks the moisture back out. I would strongly recommend  having the headers coated both inside and out. This yields multiple benefits.

  1. Ceramic coatings will help with a reduction in understood temperatures.
  2. Your headers will last a very very long time.
  3. Improved appearance.  Today's coatings can also be tinted to some degree.
4. Most importantly by having g the inside coated the heat stays out of the metal and is reflected which causes a low pressure area in the primary tube that can help exhaust evacuation from the exhaust port . This can mean a slight improvement in power.
One side note, a friend of mine had a set of nickel coated headers that he wrapped with Thermotec header wrap. The headers retained so much heat that they formed a sag. This was for a 170 cid straight 6 Ford engine where the header is below the intake manifold.
I use a place in Joliet Illinois for my header coatings and my headers look as new today as when I installed them. Contact your header manufacturer for verification or recommdations.

Hope this helps,
Terry

P.S. These coatings can also be applied to exhaust manifolds for the same benefits and CAN be tinted to mimic the look of new cast iron.

I know this is an old thread. But I'm new to building one of these engines and new to this site. What oil pump are you using? CadCo or self modified?

Started out with an MTS modified pump and went a bit further.

Despite low rpm, those engines running on up to 150 octane
gas and some water injection, were developed with outrageous
boost to manage 1 hp per cubic inch.  The engine speed is not
the prop speed, they were geared, and the prop (up to 13 feet
dia and with an increasing number of blades) had to be
variable pitch (toward constant engine rpm) to be competitive.

Thanks for all the input.  Have read similar oil articles on GM 455 engines too.  Today I drove my 472 powered Cadillac and kept it around 70 mph, never going past 2,800 rpms.  Good to know nonetheless.

Is the Cad Co pump comparable to the MTS pump? And what mods did you ad? MTS, which is now CHP has pending court action in I think three states. So I won't deal with them.

Do you have a link to the story?

That would be an interesting read. I have never been done wrong by MTS in any way. I haven't dealt with them since the passing of Marty. I've honestly had no reason to.

After Marty died company changed names three times. From MTS to another company and to Cadillac High Performance. Went from CA to FL to IL. or IL. to FL. I know the IL. Was an article in an IL. newspaper. BBB went after them for non delivery of parts and services. Was on the H.A.M.B., Cadillac Magazine forum and I think another Cad forum.

I recall about 93 buying a trans support from, I think, the original
MTS in Gardner, MA.  He was bought out by Max in Delavan WI. 
This was not far, by a long time friend, and I was over there a few
times, bought smaller parts, fixed some ECUs, and even fixed his
trailer wiring on an IL trip.  Saw his 69 Eldo drive train in a Corvair
race car.  He had a big customer party with some interesting vehicles
showing up, then MTS was sold to Marty.  I did buy some EFI temp
sensors, but those sold out, and our Scott Kent has redesigned them. 
Have not had MTS contact since then.  Bruce Roe

It's a real shame to see a quality supplier of parts and services to take such a nose dive.

Greg. Do you have better pix of the oil lines and an explanation on where you are drilling the block?

Max in Delavan?   I remember dealing with an Al there just before it went to Marty.   Marty was obviously what gave the company its drive and direction because they sure got lost after they lost him.
