I’ve searched forums, but did not find an answer to this question.

67 Coronet, 383. Engine rebuild is nearing completion. I am replacing the full exhaust system at the same time. I am replacing the original log-style manifolds with 68-69 HP manifolds P/N’s 2843992 and 2806900. It appears that I may have accidentally purchased head pipes for a 440 with the manifolds listed above.

Can anyone tell me if the 440 pipes will work on my 383? I realize the 440 is taller and wider than my 383.

Thanks for any guidance.
TTI shows 2 part numbers One is 2.5 inch and the other is 3.0 inch. But for B and RB so I think you are safe I had to edit this because I goofed on the part numbers.

THis is the page for the correct down pipes.

As long as it does not an "H" pipe connecting the two pipes, they will fit.
