    In 1968, Shelby production ended at the LAX location and was switched to the A.O. Smith Company in Livonia, Michigan. Ford brass felt that better control of the Shelby operation would be possible at the Michigan location. The ’68 Shelby front end was restyled yet again, and with very nice results. The front end was again produced in fiberglass. The ’68 cars were furnished with a twin-scoop fiberglass hood. The GT500 still came with the Police Interceptor 428. Again, a few of the GT500s came with the 427 engine, this time the low-riser version. For ’68, the 427 could be had only with an automatic transmission. Some big news for the ’68 GT500 came later in the year when the Cobra Jet version of the 428 became available. This engine replaced the Police 428, and the cars equipped with the Cobra Jet engine became known as the GT500KR. The KR suffix stood for “King of the Road,” a moniker borrowed from a popular song of the time. The CJ 428 was rated at 335 hp, a very conservative figure, most likely provided to appease insurance companies. Most sources agree the Cobra Jet 428 cranked out around 400 streetable horsepower.

    I took a look at that article. Seems to be a number of inaccuracies.

    Sorry, no 68s came with 427s installed. I recently read an old book from the 80s that said only 50 68s came with 427s installed. Funny how stories get started.

    The 427 low riser, automatic combo made it way into 357 Cougar's that year but never into a Mustang or Shelby.

    I always wondered how those Mercury guys pulled that off. There's probably an interesting story behind it. Its like they found the mother load of 427 engines when no one else could get them...

    First off, to my knowledge, NO 68's were built at the Los Angeles facility. None.

    Sounds like this is the kind of "let's make a plausible story about why MY Shelby no longer has the original engine" syndrome.

    The 427 was supposed to be offered as an option in mustangs in 68 and even had a designated "W" engine code but no documentation has ever surfaced of any cars being built with this option.

    At least some parts from a 427 low riser made it into a 68 Shelby. I was surprised a couple of months ago when a very early KR was in my friends Shelby shop for some detail work . When the engine was being detailed he noticed that one head was a 427 low riser head and the other a Cobra jet. The interesting thing was the low riser head was the one on the driver side originally and had the Ford VIN stamped into it. This would be the providence needed to verify that it was the original head on the engine. I would never have guessed this would have happened. On close inspection the dimensions of the low riser head were identical.I had first thought that this would be improbable because of differences but other then casting numbers they were the same . They even had smog ports. This must be the same head that came on the 427 cougar engine because I had seen pictures showing it was a smog engine like the Cobra jet. I always read that the low riser head is what Ford used to make the Cobra Jet I just never realized how close it was.I have got to remember to send the info and Vin to Vinny Liska at SAAC because i had forgotten it until reading this thread.

    I came across this on another web site confirming what Bob saw on the 68.

    Hello to all.According to Ford no W code engines ever made it into any mustang or shelby cars.The cougar was known as a G.T.E. and was scarce and expensive.Apparently the reasoning back then was a potential cougar owner was willing to spend more on options,than a mustang owner.It was a thermactor equipped engine,and was available only with a c-6 Just as an X code 390 2 bbl. The brochures that were printed in 68 created the myth that a 427 would be available in a mustang,and the media let it blossom from there.If you have a copy of the old book Mustang Does It ! they actually show the ad.Hope this helps!
