Excellent trade. The Corvette has to be worth upper teens in rough condition and mid 20s if a nice driver. Mid to upper 30s restored. I would remove the DZ 302 and sell it for big bucks to a Z28 restorer then put in a Fast Burn 385 GM crate motor. If you want to get more involved with the Corvette check out our Corvette site. Trucks and Corvettes mix well.
