Thanks for posting this. Now I know mine is one of 326 429 SCJ 4 speed Mach 1s.

 

The numbers check out with Marti's book which is where I assume they came from.

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.

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!

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!
