1972 was at the beginning of the swingin' seventies, when a new sound called disco was first being heard, and almost everything was getting bigger: our hairdos, waistlines, and automobiles. And so it was with the 1972 Thunderbird. Just about ready to give up any claim to being a sporty vehicle, the big, bold, new Thunderbird was brand new from front to rear. The same 429 Thunderjet V-8 engine that had powered the Bird since 1968 returned, but was now joined by a larger optional engine, the 460 V-8 from Lincoln. The sales brochure listed a 2-barrel 400 V-8 engine as standard equipment and the 429 as an option, but it's not believed that any were ever actually built with the 400 engine.-Automotivemileposts.com
The only response to this question was from another idiot (I won't mention his name here) that stated that it was a "performance motor" and he'd bought one for himself for a mere $70
I found a running one here in a 71 t bird, and the whole car cost me $70. lol. they're out there.Most Thunderbirds and LTDs had 429s or 460s in themI don't think f250s had cobra jets? and the t birds asnd ltd will have thunderjets, in most cases..and almost all your accessory brackets will need changed as they are typically attached to the sidewalls and fiirewall on a tbird or LTD, new motor mounts, and a c6 at least, if ur looking for an auto.andyou just need big block motor mounts.. they should attatch just like small block ones... but theyre... bigger..if its running, its not worth $700.... if its recently REBUILT, it might be. a stock 429, while a wicked powerplant, cant hold a candle to a well built small block... it weighs a ton more.the swap will be expensive, for all accessories and bracketry... if I were you I'd reconsider.
