IL WTB eventually OEM 68 327 INTAKE MAN & CARB

[Furno68C20]

Hi, I'm posting this to see what available out there and price. I have a 68 327 Automatic trans with aftermarket intake and carb. I want to restore the engine it back to its original build. My block casting # 3858174

My research says i need:

3919803 intake

Cast iron Rochester 4-bbl, riveted oil splash shield, temp sending hold plugged.

Also, looking for Original valve covers. One hold per side. (PCV and Fresh air)

Thanks guys. again just seeing whats out there and price.

Pretty sure I can help out with the valve covers. Have two sets of the earlier 350 valve covers. Need a clean, prime and paint but no dents or dings. Will add pics later to this post. Had to stop and think, do you have oil fill tube in intake or twist cap on valve cover?

Also if needing one I have a Rochester 4GC 4 BBL air cleaner in the parts stash. If interested in it I can get pics taken.

Thanks for the reply! The valve covers won’t work because I’m looking for the oil fill tube on the intake. But please post the pic of the OEM air cleaner and price. Thx

I have some intakes. Do you have a casting number and date you are looking for.

[davischevy]

I may have valve covers.

My all original '68 C-20 CST has a 327 & TH400. My research indicates that the correct carb would be #7028212. I thought I read somewhere the the even numbers were for auto transmission vehicles and the odd numbers were for manual. If anyone can confirm this that would be nice too...

I will check the number on my intake manifold in the morning.

When I was researching to find the correct carb for my '68 396 engine, I found that the odd 7th digit could have meant manual transmission OR turbo 400. I could be wrong, but believe it has to do with the kick down switch.

Pics of the 4 BBL air breather I have. Measures 4 7/32'' at carb throat opening which is correct for the Rochester 4GC 4 BBL carb. Very nice condition both inside and out minus the dust and dirt accumulation. Air horn is straight with no dings, rubber gasket intact. $55 plus shipping is what I'm thinking. Would do $75 plus ship after a bead blast, prime and paint. Rather hard to find a decent example without a lot of rust. Let me know if have further interest.

You would be correct Leon, even numbers for manual and odd numbers for automatic transmission.

Bummer, I've got a correct 2 barrel carb intake I pulled off of my 68 327 earlier this year. Good luck!

The number on my intake is the same as your research shows. 3919803. Under that is GM 1. The number is just behind the carb. I am the second owner of this truck and it is completely stock....

Carb info

[Ironhorse]

Rods, thanks for posting that. That is some great info to file away for future use.

4 BBL air breather SOLD to Furno68C20. PM sent with info.

[southern parts]

According to my Hollander , the right intake for you is a 3931575.

[Furno68C20]

I see that. I wonder if there are any casting differences from the two. Is there any other way to narrow down the correct intake? suffix code? or block stamped ID?

[Furno68C20]

4BBL air breather received yesterday. Thanks again ironhorse!

Thank you for this helpful discussion. One more comment resulting from my own investigation.
If you like, compare with my build sheet 26 CARB. -8213 (Excel field D6), 1968 327 with M49 (TH 400 Turbo hydramatic)
Interesting opinion from here:

http://recarbco.com/tech-help/oem-numbers/

T: Transmission. Even numbers are automatic trans, odd numbers are manual trans. Rochester also doesn’t always follow this rule.

This guide is just that: a guide. It is not set in stone, because it is a documented fact that Rochester didn’t follow these rules 100%. It is for Quadra-jet carburetors only. Rochester also had different numbering systems for their other carbs besides the Quadra-jet. Our thousands of pages of information on this comes straight from Rochester.
Keep in mind that just because the OEM numbers between two carbs may be different, it doesn’t mean they are different carbs. It’s very possible to have two carbs, their date is 2 years apart, one is for Buick and one is for Chevy Truck, and one is for automatic, the other for stick, and the carbs are identical in every single way, even down to the jets and metering rods. It’s much more common than you might think.

Also, many people think they have to have a carburetor with a certain exact OEM number. This can sometimes be very very hard. Most people don’t have to have this, they really only need a carburetor that crosses over the same and is identical. You realistically only need an exact OEM number if you are restoring a car back to original condition to enter into a car show.

Thanks for that info Gerhard. I think that scenario is more common than we all think, and not only for carbs.
