I have the option of buying a chrysler family flathead 6 with engine number t14759570, does anyone know what this is out of and the displacement

First part (T147) indicates that it is out of a Dodge truck. But I don't know enough about Dodge trucks to say what year or displacement.

A web search indicates that it is a 1950 Canadian truck engine: T Flathead Six Engines

Sorry for the late reply--Dodge truck engines do have T-numbers...my 50 Motor Manual skips T147, lists T146, T148 etc, but this manual lists mainly over-the-road models, specialty types often don't appear...

ALSO, if that is a Canadian engine, I've read that some Canadian CCptn engines don't take all the same parts as a US built engine of the same model, so double check parts info. Good luck.

Canadian made Chrysler engines were different from American made in that Canada only had one engine block while the US had 2, one for plymouth and Dodge and another for DeSoto and Chrysler.

All Canadian made engines used the larger DeSoto Chrysler block. It measures 25 inches long at the head while the smaller engine is 23 inches.

Your T147 it a 228 cubic inch model used in Dodge trucks. The same displacement engine was used by DeSoto from 1937 to 1941, certain Dodge truck and industrial engines, and Canadian made Plymouth and Dodge cars up to 1959.

It has a bore of 3 and three eights and a stroke of 4 and one quarter inches. parts are generally available for repair and rebuilding, I believe the same engine was used in Australian made cars and trucks up to the early sixties.

thanks for the info all very informative, does anyone know how far you can bore these out

The same block was bored to 3 and 7 sixteenths for the DeSoto and Chrysler. The same engine for industrial and marine use was bored even farther then sleeved to 3 7 sixteenths with hardened sleeves.

And engines in those days could be rebuilt several times, with a maximum overbore of one eighth or more. Some Olds V8s could be overbored one quarter inch.

Today sonic testing will tell you exactly how thick the cylinders are, but the old flathead Dodge engine has very thick walls by todays standards.

3 and 9 sixteenths should be safe for your engine maybe 3 and 5 eighths if it does not have core shift or corrosion problems.

A 265 bored one eighth over will give you 283 cu in. With a few common hop up tricks it should be good for 15O to 2OO Hp.

For the largest dislacement flathead Chrysler look for a 265 cu in Chrysler, Dodge truck or industrial or marine engine. This is the biggest they made and has the longest stroke, 4 and three quarters inches. This crank will fit any Chrysler DeSoto block and uses the same pistons as the smaller displacement engines, but you must also use the accompanying connecting rods that match the crankshaft.

Incidentally a guy named Don Coatney adapted a manual 5 speed transmission to his flathead powered 48 Plymouth sedan. It cruises easily at 7O Mphand he drives it all over the US. Detailed pics of the conversion are on the web if you do a search.Try Don Coatney Plymouth transmission or similar.

An Australian Chrysler from the early sixties with the big fins, a hopped up flathead and a 5 speed would be a great car and turn a lot of heads.
