Hey guys, can any one tell me the differences between the Original 3932472 intake and a reproduction one ?
-
Ok lets try this again, 79 views and no one can tell me if this is an original 472 ??
-
My opinion is that the intake is an original.
IT looks to have the correct plug in the oil fill hole as well.
-
looks original to me as well, but I'm not sure I've ever seen a reproduction. How long have they been making repros? Who makes them? and what are the issues?
-
I would think the date under the heat shield might give you the answer. I bought one from a dealer at a parts meet with the cover removed for viewing the date. Dealer said that was proof.
-
I think OER is producing them. Jegs, Classic Industries, NPD, Ecklers, are selling them. Price 380.00
-
For me its always the date code Font and Format. Unfortunately on the DZ 472 you have to remove the heat shield to see it. 472s are similar to the 163s BBC from GM. First pic is a repop date code second and third are real GM.

A thread I started here some years ago asking a similar question:

Don't know that I have seen a repro. But I would THINK some of the difference would be in the texture of the casting. Casting procedure has changed since the originals were made.
-
Looks like I jumped the gun... Repop 3932472 will not be ready until end of Dec. 2020.

Appear to be available now from jegs, C.I. and O.E.R.
Seems the difference would be the date under the pan

All 3 pictures from those companies appear to be the same generic picture. I doubt that picture is of a repop intake, as it has the brake booster fitting, and heater hose fitting with what looks like coolant pitting, and it also looks like bolt head wear marks on drivers side front flange.
I would like to see 1 in person as I bet there are differences in the casting or finish.
-
Classic Industries/OER has been putting stuff in ads that does not exist yet for years. You place your order and you go on their "backorder forever" program. Once they get enough orders, they look into producing it.
It might happen some day. The only difference you can see so far is a real one is about $650 and works while the imaginary one is $379

My thoughts too. Often will run a generic ad posting a pic of an original. Then when it arrives at your feet it looks nothing like the pic.
Without flipping to view under the pan, I bet you'll notice a huge difference between the two when side-by-side.
-
I didn't even know there were plans to repop that manifold.
-
Yeah not sure on the repop, but Chevy did make a service replacement of the Z/28 manifold. They made 2 versions, maybe 3. One with a fill tube, one with the fill tube area cast over but can be machined, and one there the fill tube area is completely gone. Only differences between the service replacement and production units was thinker flanges at the ports and a bowtie on the back runner on the replacement intake. I have 2 of the intakes and unless your really look and know how to spot, most assume is a real deal unit as it has the snowflake in the right spot.
-
The snowflake is the Winters Foundry marking, found on all the aluminum parts they cast which include many different Aluminum Chevrolet manifolds and even big block heads I believe.
I'm suspecting that the 3932472 casting number was NOT on the manifolds you referenced, camaroboy??
-
They make the 427 tripower intakes repop. Ones with part # are more expensive. I have not seen one in person but pictures look correct.

I was referring to intake 14044836, it doesn't show in many books as it was a over the counter unit. Never was used on production motors. It was cast at the Winters foundry so its a GM part and passes the quick eye test. Its like how people can mistake a L79 intake for a Z28 they look close but unless your really doing some serious judging where they are looking for that stuff.
-
GM, and the aftermarket, cast/sold many manifolds that were essentially 'copies' of the Z28 design, but had differences in appearances if you looked, and always had the manufacturer's mark and the PN...
