The big Caddy's build a ton of torque! There's been a couple projects on here with the big 500 incher!!! There are some good parts out for them, but with the big inches they don't really need a lot of aftermarket stuff. Doubt there's much around for used performance Caddy parts. Also Pat McCarthy has had a number of cams reground, probably the company would do a Caddy cam, too. I've had visions of one stuffed in an F-100 pickup, but being a Ford guy I seem to always stuff a BBF in all my stuff!!!! I'd say if you could find a decent engine and trans the price would be ok because of the low demand for the engines. Whatcha got on yer mind to put the beast in????
