My engine is block number: T245-56347
Can anyone tell me what year it was produced and the cubic inches?

Or, direct me to somewhere on this forum for the info.

Thanks,
Jerry

that would be the stock motor for an American dodge m37. the T245 230.2 cid "short block" L head with 21 head bolts and a 23 inch long head. the 230 weighs in @ 606lbs bare and -----with accessories. the 230 has a standard bore of 3 1/4 inches, a stroke of 4 5/8ths inches, with a 7 13/16th inch long rod

56347 would be the serial # (?)

3.8L if you wanted the conversion number....

And if you don't want that lump taking up space around your shop, I'll relieve you of it! ( I need one )

My M37 final assembly date was January 1954, and the engine code from the Chrysler build card was T245-60264, so your engine block was likely built sometime prior to that date. While the vehicle and the engine serial numbers probably don't track one-for-one, you could approximate the manufacture date of the engine by counting backwards using the production data on this site. Subtracting your engine's s/n from the one on my build card shows a difference of 4,277 units. Backing up the same number of vehicle serial numbers would put you into 1953, likely September or October.

Thanks to all contributors. It's exactly the info I needed.

Date codes on the castings showed June 53. And now know why it was deadlined. Number 3 rod is not pretty. I think (hope) I can save the crank.
Also, it was rebuilt in 56 with +20 bore and +10 rods and mains. Since then it spun a bearing and supported a few generations of packrats. The clutch was brand new when they blew it up.
Got it totally disassembled without breaking a single fastener! That doesn't happen often!
