How much horsepower does a 1967 mustang 428 cj fastback have?
The 428 CJ wasn't released to the dealers showrooms until April of '68. They were first run at the '67 NHRA winter nationals in '68 model factory sponsored cars. The best the '67s had was the 390. So if you want a 428CJ start saving your bucks for a '68 model. And I mean a LOT of $$$$$$$.
##Added: The '87s didn't have them either.
