Hello,
I just acquired a 1968 Firebird 400 HO 4sp coupe. It is a survivor car with 1 paint job. Original power train, engine WQ (vin on block), trans and diff.
Previous owner swapped intake, carb and distributor and discarded them. I am looking for the correct date coded parts to reinstall.
Cowl tag is 09E LOR Body 4185
Invoice date of 10/06/1967
Engine date G 11 7
Head dates F 27 7
When did the intake, carb and distributor get installed to engine?
Thank you

You would want something dated anywhere from 5 to 2 weeks prior to your build date, although a date even a few days to a week earlier would not have been unheard of. Car builds were sometime held up waiting for the correct parts.

Welcome to First Gen Firebird.

My 400 HO Convertible is a 09D built car built the week before yours. You want to find an intake G or H date. Your head date is real early, earlier then I would expect but may be correct. What in the number on the center exhaust? I have been trying to gather the correct dated parts for mine and I use G or H or J depending on what I can find. MY distributor and heads are H. The carb is dated by the day so my carb is 216 of 67 it looks like 2167. You will have to look for a Day Julian calendar for 67 to come with a day before yours was build.

Check out www.firebird400ho.com and register your car in the registry.

Thanks for the info,
I was digging around my stash and found a 7028271 XP 2637 carb. 9/20/1967
Heads are casting #216 and look to be original.
Does anyone know how and when the engine was dressed on the assembly line?

Welcome. Although I don't believe there is a timeline, the assembly process is an interesting read. The CRG Research Group "The First-Generation Camaro Assembly Process" is likely applicable for the 1st Gen Firebirds too. See: http://www.camaros.org/assemblyprocess.shtml

Welcome,

Good to see another 400 HO on the road still.

What color is it? Did you get your PHS docs for your car?

WOW how lucky is that!

I have only heard Firebird 400 HO had #16 heads. Not sure about the #216 head but Wallace Racing does list a 16/216 for 68. I would have thought F 27 7 Jun 27 67 would be for a 67 dated head but Wallace Racing shows as 68 16/216 head. I would like to hear from others about this and details about the #216.

Here is a couple of photos of my engine dressed out according to my research and should be pretty correct.

I would love to here more about this heads also

You look to have the correct Long branch Exhaust manifolds too. Awesome!

Interested in those 216's as well, I have only heard about 16's on the 68HO's, especially the early ones like yours and mine. Mine is Dec. 67 build.

Thank your lucky stars you have that 7028271 XP 2637 carb!!!!

Talk about expensive and hard to find...

There was even a poem a guy wrote on this web site a few years back about these carbs... pretty comical.. lol If you search that number on this site, you might find it.

You got lucky on this find, good for you!

The engine build number is 008531 if that has anything to do with the 216 heads. Seems to be very early production. Maybe this is what was stockpiled at the beginning of the 1968 production start?
