There's some good reading at
http://en.wikipedia.org/wiki/Ford_FE_engine regarding the differences between the standard 428 and the CJ/SCJ versions. Or, google "ford 428 cj" and read for a while.
Unless you're planning some real high-rpm work, which any 428 isn't suited for anyway, it should work well for you. And, they're getting harder and harder to find. A torque monster, for sure.
My Dad had a '69 Torino Cobra with 428 CJ. When the engine went south at around 100K (back then, 100K was a LOT of miles!!), they stuck a standard 428 in there and it worked just fine. Probably down 40-50 peak HP to the CJ, but, unless you're cranking on it all the time, it's not that noticeable because most 'normal' vehicles spend their lives far below MAX RPM. A CJ, or other mild cam (the old Crane "Fireball" was a good one), some intake/exhaust work to let it breathe, and you'd be hard pressed to tell 'em apart in real world conditions.
