Several years ago I purchased an NOS ford H-pipe with the follow part number on a tag still attached to the pipe. C5ZZ 5246-K.
Kind anyone gross reference this number to see if it is for a standard dual exhaust 289 or a "K" engine. I have attached it to my "K" engine and it seems to fit the HiPo exhaust manifolds fine. I thought there was a difference between the standard H-Pipe and one for the "K" engines.
