It came off a 75 360 and has the larger ports. What "bell"??

Maybe this will help...

So you are saying the manifolds are mismatched from 72 up?? Because the passenger side has it. I'll try and get a PIC of the ports.

340/360 passenger side manifolds will have the bell (as will 273/318 manifolds). 273/318 bells will have a smaller ID.
340/360 driver side manifolds will not have the bell (273/318 manifolds will have it). That's how you can tell the difference very quickly.

Should read # 3614388-2 to match with 3418623. 340, 360

I have one of the 3880905 driver's side a body 360 manifolds. The port size is the same as a 360 truck manifold that i have, i measured them just this morning.
The openings are approx. 1 1/8'' on the single ports, and about 2 15/16'' across the middle port.
The a body manifold has a bell at the bottom of it and the exhaust pipe attached was 1 1/2''.
I think they changed the manifold for a 360 a body for '75 to a bell outlet as well as the bottom of the manifold has extra material cast into them to cover the air ports in the head.
I took pics if you guys want to see the comparison.
I hope this helps.

Yes. I know that. These are not a "matched" pair, but he ran them as a pair.
Anyway, still for sale, and he might split them if needed.:happy2:

I'm not sure I understand something on manifolds... why are they not a left & right, matching, (Not sure I'm saying this correctly) Why aren't they symmetrical? I know partly due to the steering, BUT couldn't have that been remedied simply by making them both the same "way" with a left bolt on "bell" on one, and a right bolt on "bell" on the other? I find this an interesting thing with the passenger side having a longer exhaust pipe, and the driver side being shorter......
