Big cars have always been fun cruisers. There was even a time when big-horsepower classics were the norm, boasting such powerplants as 409, 396, 427, 454! And true to form, the last of the breed even got the potent Corvette LT1 stuffed beneath its long bonnet. While most might aspire to own one of these brawny behemoths, the more plentiful underpowered big boat cruisers can be just as much of a cherished ride, and maybe more so when you transplant late-model technology.
