tried to post on an old thread on this engine but it didn't take..so....... I'm attempting to research out a '41 Mack Open Cab ex-mil fire truck ( although given to a municipality in '42 due to a war industry facility being in the town and the town having no new truck). Engine tag says EN330-416D.. its a Type 45 Mack.. While looking for EN330 engine spec's in my Motors Truck Manual / First Edition which covers those years, I find no ref to EN330 engines.. My Mack Fire Truck book says type 45 Macks had Continental 290 or 330 CI engines.. There is a continental engine close to the 330 size, the M6290 38B @ 329.86 CI.. Any one know what I am looking at or should be looking for? Wrong tag on the engine or it was replaced.. or? Doing this research for the group that has the truck..so I can supply them w/ all specs..pic's enclosed..taken today.. Thanks, Mike W
