Hp manifolds question

[Sonny]

Is it true that any year 440 high perf exhaust manifold will fit any year 440 engine? I know I have to make sure it’s for a b body.
Thanks!

Yes but keep in mind that the 68/69 manifold and the 70 manifold have different head pipe flange orientation.

The terms "bolt up" and "fit" can be worlds apart sometimes.

You could say "bolt up" to any year 350-361-383-400-413-426-440, from any year, motorhome head and hemi excluded. But you may have to be pretty creative at the muffler shop.

Also 67 hi po manifold outlet is different from 68/69 on one side - driver side I believe but could be mistaken. My GTX has what appears to be a complete 68 GTX motor in it including manifolds and when I ordered TTI exhaust they had to substitute a 68 head pipe for the one side.

The answer is simply yes.

But as someone else said, you might not be asking the right question. The factory used different manifolds for different year cars that will add a level of complexity when purchasing pre-bent pipes. If the rest of the exhaust will be custom built, it probably does not matter which manifolds are used.
