Hi wombat46
Glad to hear you picked up that truck.
Like the guys say--that should be a 248 engine.
There should be lots of advice forthcoming on how to get it going and here's my idea on how I'd try.
You have to know if the engine is seized or not.
Pull the plugs out and see if the engine will turn over. Before you do, spray some lubricant like WD40 in the cylinders and let it sit awhile. Try to turn the engine by turning the fan and belt. You could jack up a rear wheel and put it in 4th gear then rotate the wheel if the fan thing doesn't work. Lots of guys on here have said they have waited days for a lubricant to work it's way into a seized engine so don't despair.
If the engine rotates probably a good idea to change the oil before starting it. Also the fuel tank will be contaminated no doubt. An alternate fuel source, jury rigged to the carb would be advisable or make sure you flush out the fuel tank before trying to run it. Be sure to have coolant in the rad as well.
When you're ready to try to start, pour a half a cup of fuel in the carburator, give it full choke and see how she goes!
These old stovebolt engines are surprising how they'll fire up from years of neglect.
If it won't run of course you'll have to look at the ignition system.
Good luck and keep us advised.
Cheers, George
P.S. Pretty sure you'll find your truck is a 2 1/2 ton or 3 ton. Mapleleaf's didn't come smaller than that in those years. They were 'heavier duty' than Chev's.
