There have been a few noted B body chassis swaps on them from the late 70's early 80's Impala/ Caprices. The wheelbase is correct between the 2, but it's still more work than is nessasary... Remove the ebrake handle, trim the firewall tabs that are on each side of the 6cyl and a V8 will fit and work with conversion mounts.. The '49-'54 Chevy suspension lived on in part until 1962 in the Corvette
