1973 Grandé
The journey actually began in June 2000 when I purchased the engine, transmission and rear end of a 1970 Ford Galaxy from a very good friend. He had an incident with the Galaxy which necessitated his getting rid of it. We were under the impression that the motor was a 429 but when I tore it down, it was determined that it was actually a 460!

At the time, my intent was to replace the 1970 428CJ motor in my modified 1973 Q-Code Mach 1 with the motor (as a Stroker) and transmission from the Galaxy since the 429 had been offered in the Mustang in 1971. My plan is to possibly use the 428CJ and Toploader from the Mach 1 in a period correct 1969 or 1970 Mustang.

Sometime in early 2001, I acquired a “parts” car in the form of a 1973 Q-coded Mach 1. While the car looked as if it had been stored in a bog from the rear window back, everything else was actually in pretty good shape. I was in my garage piddling around when a young Man drove up in his ’73 Grandé. He had heard of my having the “parts” car and was looking at possibly obtaining it. He noted that he had purchased the Grandé and made some changes to it with the installation of a “ram air” (NOS) hood, 4V Intake, Carburetor and a couple of other minor modifications. We had an interesting conversation culminating in my providing some advice as to other options for him as I did not believe his obtaining the “hulk” was a cost-effective way for him to go.

Approximately two weeks later, I was driving to my office and noted the Grandé on the side of the road, apparently broken down. About a month after that, a local “automotive procurer” expressed interest in what I had left of the parts car. I journeyed to one of his storage sites where I determined he had obtained the Grandé and had already pulled the engine and transmission. We made a deal whereby I gave him the “hulk” and $500 for the Grandé. Prior to turning over the “hulk”, I pulled the grilles, console, gauges, transmission, rear end and a number of miscellaneous parts.

I had already decided I wanted to do a “dry run” by building another Lima-based motor (429/460) prior to building the stroker motor for the Mach 1. I felt the Grandé was a great platform to build a relatively “MILD” motor along the lines of what I believe would have been Ford’s approach if they had continued their alleged intent to put the big block motors in the ’72 and ’73 Mustangs.

I located a small obscure local 2-man machine shop and approached the owner about building the motor to my specifications. This work was actually completed in early January 2002. I also found an independent transmission builder in another County who agreed to build the transmission to my specifications.
It should be noted that during this time, I was gainfully employed as a traveling Investigator for the U.S. Treasury which kept me on the road nearly half the time in a given year. I really did not have time to work on the “project” except in short bursts. I retired from Treasury in 2009 and soon after started to get serious with the effort.

I installed the “new” motor, rear end and transmission into the Grandé. I also did the interior to include adding a new dashboard, and the console and gauges (from the “hulk”).

In June 2010, I turned the Grandé over to a “Restorer” with a contract specifying completion of body and paint work within four (4) months. True to what appears to be the “norm” in these type transcations, the work was not completed until August 2011.

Congrats..Looks really sharp ! I like the 472 emblem on the hood.. How about a video of it running Tongue

Great looking car and history to go with it. I think you should post it in COTM on the road. Any Chevys fall victim to Ice yet? Chuck
BT Did not see cam specs listedHuh
I have edited the post to show the cam specifications.

...and No, I have not had to confront any Chebbies yet.

I will try to get a video up as soon as I can.


Do the RIGHT thing.
