WTB: Big Block Exhaust Manifold RH 3909880 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

gregbr · 02-09-2008, 10:46 AM

Just got the truck back from the muffler shop, nice new stainless exhaust and one of the flange ears broke off!!

Anybody have a factory Big Block exhaust manifold for the passenger side...stamped 3909880 for my 70 402? It does not have smog holes and it has no raised casting lines like some I've seen. Must have no cracks, no broken ears or stripped threads. I will clean & paint it. Let me know what you have and $$ with shipping to 29730 in South Carolina. Paypal waiting. THANKS, Greg

**BIG ORANGE** · 02-14-2008, 11:53 AM

Greg I still got the ones that came off the 402 in BIG ORANGE I'll look the next time I go down to the other shop, cant remember anything about them!

gregbr · 02-15-2008, 04:19 AM

Thanks Rob & Big Orange. Let me know if you find anything. I will contact Uncle also. Greg

**Hart_Rod** · 02-15-2008, 02:24 PM

Or you sure that part number is factory for a truck? This site says that part number is for a 1967.

Don't know for sure Rob, that't what was on it when I got it 11 years ago. It's 98% original numbers on everything, so I assumed it was correct. The 3916178 appears to be more correct by the different casting number books. Greg

I have a set that I know came off of a 1970 402, if you are interested let me know.

gregbr · 02-16-2008, 10:04 AM

Let me know what casting numbers and dates are on them.

After talking about the 3909880 showing only on 67 models, it hit me to check the casting date on mine. It's Sept 69. So, it could be correct?? Greg

It will be next week before I can get you the numbers as I'm in FL right now. I'm not sure about yours, I've seen crazier things as far as the numbers go. Just let me know what you want to do.

gregbr · 02-17-2008, 10:10 AM

Let me know the numbers on yours when you can. Greg

**Hart_Rod** · 02-24-2008, 07:09 AM

Hey Greg, I finally got a number. My right hand side is 353028. Here's a picture.

gregbr · 02-24-2008, 04:13 PM

Thanks anyway Rob, but I don't want the smog holes. Greg

70cstjr · 02-24-2008, 09:21 PM

my father 70cst has a set from his 70cst 402bb i do not know if he will sell right now or not or even separate but i can try to find out for you

gregbr · 02-25-2008, 09:16 AM

Thanks Rob....

Thanks 70cstjr, Let me know the casting numbers & a price if he wants to sell. Send a pic if possible, my e-mail is listed below if you need it. Greg

rawraw67 · 02-26-2008, 09:23 AM

are the manifolds the same from lets say 1970-1980 ?

gregbr · 02-26-2008, 04:13 PM

I think this casting number is used on 67-70. The 71 up were different casting numbers, but alot of them will interchange. I'm currently using a 74-76 454 manifold on the passenger side, casting 353030. It works fine, just looks a tiny bit different and has different casting numbers and date. Greg
