Flat head engine

I bought a 1936 Oliver 70 last week, that someone had pulled the Waukesha engine out of, and put in a flathead 6 cylinder. The guy I bought it from said it might be a Chrysler engine. A neighbor stopped by to see it said he's sure it's a Dodge engine. How would one find out what flathead 6 engine this is? Any ideas what C.I. it might be?
 
Well first of all all Oliver model 70 tractors used an overhead valve Continental, not a Waukesha. The easiest way to tell an L head Chrysler from the 6 cylinder Continental F series flat head engine is by the location of the engine oil pump The Chrysler engines have the external oil pump on one side of the block and the distributor on the other side and they are mounted at an angle. The Continetal if it has a distributor will have the distribtor mounted on top of the cylinder head. The chrysler could be a 201, 217 251 or even a 265. Got casting numbers?

It will tell you what the engine is out of. I believe Oliver used Chrysler engines at one time. The set of rings I put in my 1950 Dodge yesterday were Hastings, listed as Oliver and Chrysler. There are two basic sizes of engine block, a small and large. Small has a head around 23 inches long are are up to 230CID. The big block has a 25 inch head and goes up to I thing 265 in the Chryslers andinductrial series. Parts are easy to get since these engines were made from the early 30"s to the late 60"s. Some industrial series engiens have sodium filled exhaust valves and they all have hardened exhaust seats so unleaded is no problem. Tough and reliable as long as you don"t over-rev them, which wouldn"t be a problem in a tractor. Watch military surplus dealers for parts. I got rings, rod bearings, and main bearings for my Dodge that I must finish rebuilding today (daily driver) for around $100 total from several surplus yards. Email me if you need any help with it.

That is a thin line. Oliver application for Chrysler engines is COMBINES ONLY, no tractors. That is also the Cockshutt designed combines not any Oliver designed and built combines. Not only that except for the last year of the L-head in a combines they are engines made in Canada and the parts are not the same for everything. They issued a seperate parts bulletin to cover the American engines.
 
chrysler also used a 230 ci. engine in 50,s. old parts hunting trick at salvage yards, 250 and 265 engines used a 2" longer head than 217/230. seems to me engine model and serial # were stamped on machined pad on left side of block, at about # 1 cylinder location and an inch down from head. had an engine from street sweeper stamped IND 265 shoe horned in 58 1/2 ton pickup, it was a real go getter when hauling fire wood. hope this info is accurate and helps leroy
 
yes agree on serial # stamping. this 265 was also used in the M.H.super 92, cockshutt 542, M.M.4292 Combines.it was a good lugging engine compared to the 318 v8 crysler that was put into the later 542 and 5542 cockshutts. the 318 would just stall and not recover like the 265.
 
The FIRST 413 CID engine Chrysler built was a L-Head ( Flathead ) six. It had a 5.5 inch stroke and was built in 1953-54 if I remember right. It was used in 3 ton trucks.
