WANTED Exhaust manifolds 2863409 2863408

[GBsPanhead]

Picked up a dual snorkel set up today from an outstanding member here. Thanks again!

Are 2863409 and 2863408 the correct part numbers for the HP, (Hump) manifolds for my '69 300 'vert? From my research I did on here, they appear they are. Please let me know, and if anyone has a set they might want to let go...PM me please.

Also, I found some other part numbers, 2843992 and 2806900. Would these also work? I think they will, but are for different model years? I kinda want to stick with the correct part numbers for a '69.

Please let me know my options here. Thanks!

According to the parts/casting # book I think you need part # 2806898 RH HP, 2863408 LH HP. 2806900 is the casting # for the first manifold, 2863409 is a casting number for the second manifold. 2843992 is a casting number for a B body LP manifold. You should be able to find a correct set. Good luck.

I found a couple threads here that had some links, that's where I got my info. It's like learning a whole new language...old Harley's I have no problem with parts/prices. Now learning old Mopar stuff! lol

I will go research those numbers you listed. Just don't want to buy the wrong manifolds. Thanks!!

I was looking up the numbers when @polarus responded, and he's got the correct numbers listed.

Thanks guys! Watching Misfit Garage on laptop, and trying to surf the 'net looking for parts!

I have the left side exhaust manifold. See:

Thanks, always good to have conformation from another member.

I have a nice left side HP manifold for a big block C body. Rust free, fresh from a molasses bath. No paint on it, just a light coat of WD-40. Has a late 68 build date. $175.00 including shipping in continental US

Thanks for the replies everyone!

Question....PO installed a dual exhaust using the stock, (non-HP), exhaust manifolds. If I upgrade to the HP version manifolds, do the mounting flanges line up with non-HP manifolds? So my duals would bolt right up to the HP manifolds, without having modifying anything. Kinda hard to explain. Would it be a 'plugNplay' situation since I have duals already, but like stated, using the non-HP manifolds. Hope my questions make some sort of sense. Thanks!

Sorry to say but no, your manifold pipes would need to be modified or changed to line up with the HP exhaust manifolds. Maybe someone can post a photo of a left non-HP exhaust manifold to show the difference.

the correct exhaust pipes are available through TTI. They will need your car information and the cast number from the manifold your using.

Thanks guys! TTI is not far from me. Maybe 35 miles!!

Thanks guys! Manifolds no longer needed.
