It's always fun when an ambitious hot rodder combines random automotive oddities to create an interesting classic. Take, for instance, a Checker Marathon and a GM Atlas 6-cylinder. Yes, you read that right, the folks over at Fuel Injection Sucks have a pretty clean Marathon sedan, and they also happen to have a spare copy of one of GM's most underrated engines. Seems like a unique recipe for success, right? 

Often overshadowed by a sea of Taxi siblings, the Checker Marathon was built for direct sale to retail customers. Beginning production in 1961, the sedan was largely unchanged until its parent company stopped manufacturing cars in 1982. Interestingly, after decades as a Tier 1 automotive supplier and, ultimately, bankruptcy brought on by the Great Recession, Checker is currently restoring cars and once again struggling to exist as a niche manufacturer.

Introduced in 2002, the Atlas 6-cylinder was a member of General Motor's inline piston truck engines that saw use in a number of the company's compact and mid-size offerings. An award-winning, DOHC mill that produced just under 300 horsepower, the aluminum engine was lauded for being smooth and torque-rich. While less than 300 horsepower might not seem all that great in an era of demonic Dodge sedans, it was very impressive when the engine debuted almost 20 years ago.

Looks like this is going to be a fun build!
