Do B body exhaust manifolds fit E body?

[Tony C]

For a 440ci engine..... would 69\70 B body factory HP exhaust manifolds fit in a 70 Challenger?

Just checked casting #'s and the comeback as 70\71 B+C body... (LHS = 2951865 + RHS = 2899879)

Yes, they are the same.

Particular ones you are asking about?

Not sure but I thought the flanges were clocked different.

The exhaust manifolds are bundled with the engine, and not the body.
The manifolds fit all the bodies the engine was shipped with by the factory.

If you're swapping the same P/N they are the same - B&E body. On my 70 Challenger (original 383 2-bbl) it came from the factory with the HP exhaust on the driver's side and the LP exhaust manifold on the passenger side. I pretty sure I had to change the passenger head pipe (was converted to dual exhaust by me prior to swapping the exhaust manifold).
