Continental 0300D

Hope this doesn't get thrown out as I am building a 9A and ready for the finishing kit.Was flying a 172 but lost the engine in flight due to a broken rod.Put it down without a scratch but engine is junk.Looking for a decent engine or core for sale.anybody know of any engines out there? Thanks

I used to fly a Cessna 172 with the o-300. When it was run out we converted it to the 0-360. What a great improvement. Can't tell you how many times tower called us 182 because of our speed.
