Truck engine from 46-48 fire truck ,would it be same as car engine i think the truck was a 1 ton or 1 1/2 ton
 
Other than the normal variation of truck related parts VS passenger car parts the basic engine is the same. The bigger 337 engine didn't come out till after 48 and that was only in the really big trucks like F7 & F8. If there are exceptions then they are beyond my knowledge.

46/47 truck engine is the same as 46-48 car engine, but 48 trucks had the new engine - like the 49 cars.
 
The 8BA engine (bolt-on bellhousing and bolt-on thermostat housings at front of heads) came out in '48 trucks, but a fair number of early '48 trucks got the earlier design 59A engine (integral bellhousing, water outlets at top center of heads).
 
1948 was the transition year for pickups & trucks. If the Fire truck was a 48 then it could be an 8BA engine. This engine wasn't used till 1949 in passenger cars. You will just have to confirm whether it has the cast in bell housing at the rear like the older 45 through 48 59A or no bell like the 48RT/49 through 53 8BA engines.

I've seen big trucks with the I-6 flathead engine too although I doubt they would have put one in a fire engine.

I've heard that Lamar, but I have yet to see one that can be verified. The sheetmetal would have been leftovers from 42-47. Couple that with some state's habit of titling a truck by year when it was sold - regardless of when it was built and it becomes nearly impossible to sort out.

All I know for sure is the new F series trucks came out Jan 16, 1948 with the 8RT engines. The serial number prefix of 88RC ran thru December before switching to the 49/50 designation 98RC...
 
if its the 59A style motor, it could have the two piece oil pan that trucks had to get the flywheel off without droping the oil pan. were'nt some truck motors factory relieved?
could also have a govenor under the carb and a larger vaccum port in the intake for the brake booster. but thats all bolt on stuff
 
A fire truck eng. has probaly been run hard & put up wet.(meaning it's been worked a lot harder than the odometer says & the truck may have only gone 500 miles to & from fires but the eng. may have run 1000 hrs. or better while pumping water,more often than not wide open.
