It can even go in place of the I6 mounts, but exhaust and clutch/throttle linkages would have to be changed. you're also looking at a suspension swap/springs/brakes to handle the weight of the BB. (also might have a clearance issue at the firewall but nothing a mallet can't fix). I'd get on a Chevy truck forum and look for posts on this exact swap, there are tons of them with detailed write ups.
