Looks like they dropped a Hopped up 351W into an otherwise stock Grandma's Monarch, body paint & interior look great. (from what little the pictures show us) They probably have more into the engine than they are asking for the car. pretty base car, Shame they hacked out the dash for a modern radio. https://seattle.craigslist.org/tac/cto/d/1977-mercury-monarch-351w-roller-gt40/6956732901.html
I guess, you could call it The Seattle Chainsaw Massacre, being that it looks like the dash was sadistically carved using a chainsaw. Cool tweek, though. The mill just fits
I know this guy! I thought the car looked familiar! He's the one I bought my Bronco drivetrain from years ago! The assertion that you're buying the engine, and it comes with a free car, is spot-on, as he got the Granada for very, very, little.
