Intake manifold what year?

[Joe L.]

Tim----

I believe what you're asking for are the Delco parts system numbers for the caps. The Delco number for the GM #800061 is, I believe, D-308R. The Delco number for the GM #800063 is D-325R.

Unfortunately, these Delco numbers won't help you very much and could be very misleading. That's because Delco parts system numbers tend to be very "generic". In the GM parts world, the Delco number, with letters and numbers, is often referred to as the "short number" and the GM part number, with 6, 7, or 8 digits, is referred to as the "long number". The "long number" for a particular part may change over the years, but the "short number" often remains the same. The GM #800061 started life in about 1968 and "co-existed" with another part number, GM #1971244, for a short while. Then, the 1971244 was REPLACED by the 800061 in 1969. In 1975, the GM #800061 was discontinued and replaced by the LONG NUMBER that it had originally replaced, GM #1971244. Very unusual, but it happened. Throughout this period, as far as I know, both caps were known as D-308R, but I am not ABSOLUTELY certain of that.

I do not know what other LONG NUMBER, if any, that the D-325R cap may have had. I strongly suspect that it was always known as GM #800063.

Incidentally, I recently discovered that the GM #1971244 cap has now been replaced by GM #12338667. As far as I know, this cap is also known as Delco D-308R. I do not know what configuration differences, if any, that the 12338667 cap exhibits relative to the 1971244.

Lastly, if anyone out there has an 800061 cap STILL IN ITS KNOWN ORIGINAL BOX, I would be interested in knowing if the Delco number is seen as D-308R.

Intake manifold what year?

I have an intake manifold that I need to identify the correct year and application. The part # is 14044886 or 14044836. The local GM dealer said I needed to find someone with an 86 or older parts list. Can anyone help? Thanks.

Re: Intake manifold what year?

I thought I was on a roll today but it is not in the spec guide up to '82. We are talking about the # cast into the manifold aren't we? Actual GM parts #s are usually close to the casting # but not the same. I don't even find anything close. Maybe it is a GM Goodwrench Performance part.

Re: Intake manifold what year?

This number is on the top near the Chevy bowtie. The numbers on the underside are 123456789, so that's nothing. I am baffled! This came off a 72 LT1. Do you know how I could determine if it's a GM Goodwrench part? Thanks!

Re: Intake manifold what year?

I justed looked in my 72 parts book. No numbers starting with 140------. Book says , 71-72 w/SP. H/Per. is 3991004. Most numbers start with 38 or 39.

Re: Intake manifold what year?

Kathy - the 140xxxxxx series numbers are all more recent than the seventies I believe. Also, the bowtie you mention probably means it was a Goodwrench performance part versus original type. Does it have the winters foundary snowflake logo? I have some Goodwrench performance parts catalogs going back into the late eighties and I will try and look it up in there.....Craig

That appears to be a......

newer casting, more like Gen V or VI. Suggest you get on

WWW.Sallee-Chevrolet.com

Try and match the casting number with their parts on line catalog.

Good luck

Re: Intake manifold what year?

Closest I can come is with manifold part numbers starting with 1403xxxx which is 1982 era.

GM started using the 140xxxxx part numbering sytem around 1979-80. Most of the old fa%^$ around here sometimes forget that they actually made Corvettes past 1967

Sorry Dale, I forgot you. 1962.

Re: Intake manifold what year?

Kathy, If it has a bow tie cast on the top it is a Goodwrench Performance part and not an oem manifold on any Corvette production engine. A real good part for a modified engine though. Tom

Re: Intake manifold what year?

Kathy, I think I have possibly identified your manifold, looking back in an older GM performance parts catalog as I indicated in my prior post. As Tom states, these are not OEM Type manifolds, but may be very close in design and function. I believe this part is functionally similar or equivalent to an LT1 manifold of the 71 era, but will not be correct at all from a judging perspective. I will describe the physical attributes of the manifold from the picture, then copy the text from the catalog. It is P/N 10185024, and has the bowtie behind the carb pad on the no 8 runner, just behind the larger flat area where the runner widens to the pad. Also, there is a casting number, typicial of the original manifold locations, just behind the pad in this same area, but there is no way I can read it from the picture. Also, on the front of the pad, it appears to show the firing order 18436572 as is typical. There are two drilled water outlets for the heater, typical of many GM manifolds, one down lower at a 45 degree angle pointing towards where the passenger side upper A arm would be, the other angling up towards the area where the AC compressor would mount on the boss area where the coolant flow exits the front of the passenger head. In addition, this manifold has the classic divorced choke pocket on the passenger side for the bimetal coil spring and housing, the carb pad is drilled only for the Holley pattern. Here is the text:

"Aluminum High Rise Intake Manifold" (header) "This single four barrel intake manifold assembly is used on 5.7 liter High Output engine assembly. It is similar in design to the high rise Z28/LT1 intake manifolds, but there are several significant differences between the two manifolds. This manifold does not have an oil filler tube hole, and it's choke stove mounting holes are not drilled and tapped. The upper edges of the gasket sealing edges are chamfered to accommodate the raised rocker cover rails found on Corvette aluminum cylinder head assembly # 10185086. (an AC bracket boss has also been added). Technical notes: This manifold mounts a standard Holley four barrel. It does not include a lifter valley oil baffle."

Hope this helps - it sounds like what you describe ignoring the casting no 140XXXXX......Craig

Re: Intake manifold what year?

Thanks a million! You have definitely described this intake. It is so similar to the oem LT1 intake with very minor first glance differences. Your assistance on identifying this intake is greatly appreciated as we will be selling this part on Ebay and we wanted to make sure we knew as much as we could about the part. We did find a correct oem intake #3959594 for our 72 LT1. This is the first time we posted and it was great. Thanks again to all who responded! Oh yeah and how this intake wound up on the correct CKY engine car...the last owner let a mechanic convince him that since the carb was bad, might as well replace the intake too. Go figure.
