they only list a continental 318 or a 350(chevy?) - but they may be able to help you
http://aerobus.homestead.com/aerobus.htmlwiki sez - 1978 and later models can be identified when Chevrolet switched to a "Delta Spoke" steering wheel design, duly used on Checkers. The rear fold-down jump seats were also removed as they failed all safety tests. The car had very poor gas mileage as the tall front end and engine compartment had been designed for a Continental 226 cubic inch inline 6, which required the large engine compartment.
In 1964 Checker no longer used engines produced by Continental. Continental had been losing money on each unit sold to Checker for several years, Checker was not interested in a price increase from Continental. Checker experimented with several engine options including the Chrysler 318. Eventually Checker went to a Chevrolet straight six. That engine, along with an optional Chevrolet V-8 were used until the late 1970s.
