1967 tri-power intake

[Jeremy H.]

I'm looking at buying a 3x2 intake, wondering if it is a repo? has anyone noticed anything different with these repos and an original?

Thanks

Re: 1967 tri-power intake

I think originals have the "Winters" logo / icon for alum intake - not sure if repos have that detail as well.

The casting date is on the underside of the manifold as well to confirm if original.

Others may be able to offer you more help.

The originals I have seen all have the winters "snow flake" on the casting.
The date on the bottom M/D/Y

I had a Dec 26, 1966 with what looked like a casting flaw on the underside in the center near the runners. To my surprise, a friend of mine had two others with the idenical "casting flaw" on the underside of his. Perhaps a mold problem; I never found out. The reason I mention it is if the date is close to the above one it may have that too.

I believe the reproductions have the "Winters Foundry" logo as well. However, I cannot figure out how the GM Restoration Parts Program can license that feature. GM owns everything about the manifold and can and does license its reproduction through GMRPP but I don't see how they can license the use of a manufacturer's identification mark (except, of course, their own, in-house manufacturing operations). I would think that the license for the use of the Winter's Foundry logo would have to come from Winters Foundry. I believe they are out-of-business but someone probably owns the name and other "intellectual property".

In general, it would seem to me that any manufacturer would be reluctant, if not foolish, to license someone to produce any part with their manufacturer's ID or logo on it. A manufacturer's ID or logo is just that; it's supposed to identify the MANUFACTURER of a part. It's like a person's signature. Would anyone license someone else to use their signature?

You are right but if they are out of business no woe is watching. I am sure that someone scanned a original & CNC'D a pattern which is very easy to do. Pattern & core box could be made for 15,000.00 or so. The date on the bottom under the heat shield was a Dino tape so they can put any date you want.

Thanks Joe, There is clearly some equity and value to that logo that one would think someone is still managing its rights. Licensing, private labeling, private branding, Ingredient marketing, it's hard to know who is REALLY making your part unless you do a good deal of research. You are right on the money though, partner with the wrong company and there goes your brand and all its equity.

Jeremy:

The 3x2 aluminum manifold reproductions are manufacturered/sold by Coffman Corvette in Ohio. They are also being sold/marketed by a few other companies across the country. David Crane in California was one of these companies.

From what I have seen, only 2 or 3 dates were used for all the reproductions.....so this is probably your best clue. These dates were listed on the internet a while back, I MAY have this info in my files, and will check later in the day. I think one was a late 1966, and the other was an early-mid 1967 date. The David Crane or Coffman websites may also have this information.

Otherwise, post the numbers and date codes on the manifold in question, others who purchased the reproductions may be able to help.

Re: 1967 tri-power intake

I know that people had issues with them not working properly.With the part being a reproduction and others having issues with them when you figure that they are not any less expensive than an original why bother

i wonder if dove engineering in ohio is casting these manifolds as they do aluminum heads and blocks for ford engines.

Intakes are not that hard to cast. Almost any aluminum fdy. can do it. Fixturing & machining is another issue. The mating surface & bolt holes need to be dead on. I assume they are made with 356-T6 alloy & heat treated. If they are made from 319 they most likely well warp. I would find out before buying one.
