I do not own a 1971-1973 Ford Mustang, but am requesting admission to the forum so that I can learn about these cars.
I own 6 1967 FoMoCo products: 5 1967 Ford full-size cars, and 1 1967 Meteor (a product of Ford Motor Company of Canada, Ltd.).

Awesome information! Not just interesting but VERY interesting!

 
Thanks for the production numbers for the 429. As a follow up question, does anyone have any experience or knowledge about the difference in $ value between a matching numbers 429 SCJ and a non-matching number but entirely correct motor? Thanks.

Just my opinion, so this is not written in stone. A "Numbers Matching" powertrain probably carries a lot of weight in the big name auctions like Barrett-Jackson, Mercum , or to a Purist who will only accept such a vehicle, to the point of not even wanting one that had a blown engine replaced with a factory "Service" block or engine assy . My circle of friends who bought these type of vehicles (Big block Chevelles/Camaros, Chargers/ Roadrunners, 428,429 CJ/SCJ Mustangs/Torino's) drove these cars as hard and wide open as they would run.

Any thought of collectability or what their car might be worth 20+ years later was not on the radar. Most of these cars had at least a 24/24 powertrain warranty so blowing one up was not a concern. So if I were in the market for a 429 CJ/SCJ 71 Mustang and it had a replacement engine, as long as it was of the same caliber as the production engine all would be fine. Those 429's were about as tough as they came.

I believe most would prefer a numbers matching first but a service engine replacement if documented should not be that big a deal. However there is a 71 Mach 1 on eBay now that is being advertised as a 429 Mach 1 which it is, but it now is sporting a 71 Boss 351 engine in its place. They go on how rare the 429 cars are and all the options this particular car has but still its no longer a 429 car. Just a strange thing to do with a 429 car in my opinion.

I'm betting someone with a Boss 351 would really like to have that engine in their Boss 351!
