On what day in 1966 did the secret Cougar marketing program begin? April 1st, April Fools day. On what day in 1968 did the Cobra Jet 428 become available in the Cougar April 1st April Fools day. Is there a message in there somewhere? This is the place to find out.
Update on the 71 Cougar Conv. 429 CJ, saw it again at a car show, was able to talk to him, it's a fake, originally a 351. Nice job with the installation of the 429, but sorry to say, no new info for the registry.
