I"ve been getting some conflicting answers to this question. Does the Oliver 70 have the F202 or F226 Continental engine? As I start to look through parts catalogs, it makes a difference. I appreciate the email that I have received over this so far. Thanks in advance.

The F-226 and your 70 which is a DS engine take the same bearings as well as some other parts. For pistons use can also use a 3.250 Dodge truck piston or a Continental piston. I would check prices first.

Using the Dodge pistons what comp ratio will you get? I've been told that the combine motor like from a 33 Oliver(226), MM also used that same motor in their combines also,will drop right in the tractor do you all agree with that? Just think of the HP increase you will get for pulling! What about the over head cam Continental from a Jeep? I believe that it is a 226 also.

The Jeep OHC cam engine was the 230 CID, Tornado Six.

The older Jeeps are F-226 automotive engines. The overhead cam engine is not a Continental. The F226 Continental engines in the Jeep are different in that they use a timing chain instead of timing gears. There is also no place for the governor. The compression height is the same so the base increase in compression is going to come from the volume from the increas in cylinder bore size. Remember an overhead valve motor is more effecient than a L-head. Questions? Find me next week when I can look stuff up.

I have an Oliver 70 which I will be working on in the future so I would like to know what engine it is. It is an later model. Just for future refernce.

Well, after my post I did some looking in some parts books and it looks like it takes the bearings and pistons for Continental ds202, ds6202 and a pd202 engines. These engines are overhead valve.
This cylinder will overbore to 3.250 with this piston setup. (From 3.1250) Sealed Power seems to make a good forged piston for this. Bearings can be scarce, but available. Parts men will tell you not to turn the crank if you don"t have to. One parts man told me the F226 for for a combine application.
If my posting is wrong, please do a correction. Thanks.
