I have a '48 F1 with a 7HA6050-C2 flathead six. I know where a OHA????? flathead six is that is about to be crushed. I believe this was from a 1950 but am not sure. Is this motor identical to the '48 except for the stamp on the head and can I use all the parts on my '48? What would it be worth?

 

They should be pretty much the same. The only thing that I have found between the different flat sixes I have had is the starters. Although you can swap complete starters the starter on the '50 I have in my '49 F-2 had a different starter than the one on a '49 parts truck I have. The armatures were the same but the casings were different.

As for value, they're not usually worth more than scrap. I have been given a few of them, most people want the flathead eights. If it was a good running engine and you could hear it run I would give up to $200 for a good running engine. I personally think the sixes are a very good engine and can take a lot more abuse than the eights. They both have about the same horse power rating.

 

mh48 Welcome to the forum, I would advise grabbing that other engine for spare parts if you plan to stay with the Flat 6. The OHA was produced in 50 and 51 but if you look on the pan rail right below the distributor the block serial number will start with 7HA on both engines. The difference is in the camshaft and oil pump drive gears, the 7HA and 0HA each use a different camshaft and different number of teeth. Each cam is stamped on the front as to which one it is. And these drive gears aren't to my knowledge being produced anymore. I picked up another 226 for parts myself and have a spare cam and pump drive gear. There was a guy on a post awhile back over in Europe who had an oil pump gear go out on him and was looking for one over here. We checked around with the vintage engine companies Egge, Kanter, and neither had a gear they suggested having one custom made. He was able to get in contact with a person here that had a spare to sell. One article I was reading the other day said the biggest reason for oil pump drive gear failure is installing a new cam and using the old pump gear. So I would suggest to always have your cam reground instead of installing a new one.
Also the water pump is not readly available and I plan to get mine rebuilt and keep for a spare. These engines are good especially with an S10 5-speed trans and higher gear rearend.

 

I agree, it's always nice to have extra parts. My wife always asked why I kept "all that junk" since I had the truck completed. That "junk" has come in handy many times when I need a part that I would have to spend weeks looking in junkyards or the internet, that is if anyone would have it. It has come in real handy on a Sunday afternoon after I stripped the brass block behind the master cylinder, within ten minutes of scrounging around in my "junk" I found the part.

I recently scrapped a flat six that was froze up but was able to send the oil pump gear to the guy in England, he said that it was basically the one part holding up his getting the truck on the road.

 

A man can never have too much "junk"!!!
