03 2v Lethargic

[96blak54]

Modular engines began strong in 1992. The only down fall of this exhaust lasher swap is noise. The engine valve train gets a bit noisey at idle. You will not find the part #'s or exact replacement parts. Best to find an old engine, old heads and extract what you need. The 1st pre95 4v 4.6l from lincoln continentals were full of them.

OK, thanks for explanation.
So it was 4 valve engines that had them: "1st pre95 4v 4.6l from lincoln continentals"
Finding one of those engines is sadly not going to happen on this side of the pond.
