Are the 1970 HP Manifolds one year only pieces? I realize they will fit most any BB, but I can't remember if the 70-71 are the same casting or if it's 70 only. Thanks in advance.
Thanks for the list. I have a set and have a person interested in buying them. I gave him a price but apparently it's low after looking around on different sites. I will keep my word but was just trying to remember what years are covered. Some are advertising as 70-74, others 70-71, and some just 70. Thanks for the answer.I updated to the full list but marked them in red.
I paid $450 for a set as you just described. No pits and a working heat riser with good bushings so no exhaust leaks around it. You will find asking prices all over the board, but it's what someone actually pays that counts.Thanks for the list.
Turns out I have a pair of the 67 440 Mag L&R.

In great condition with the heat riser, Any idea of value?
