enjoyable reading this read, after owning a couple old Fords, and working on more than a few of them.
I recall when I was about ten, we pulled into a Mercury dealer to pick up a new Mercury sedan. Parked right next to a 69 Mach I. Man I was smitten with that car. I didn't appreciate it at the time, but the Marquis Dad bought, with the 429 pre-emission motor, was a beast of a sedan, too.
Is the 390 motor original to the car? In Dad's garage they did a valve job on a 390 that belonged to a college student. It was marked 390, but when they got the heads off, it had the 4 1/4" bores of a 427
I'm getting that car hankering again. The new truck isn't going anywhere, but the 04 may get traded or sold to fund something interesting.
