I pulled the 230 from my 66 moredoor this spring. It was running strong but had oil issues...I'm in the prossess of taring it down now....I don't know if the exhaust valve is bad in the #6 cyl or not. could be the rings....but I plan on taking care of that issue..I'll put new rings in it..Clean it and have the valves done if I have too, to try to resell it..It has about 177000 miles on it but I'm not sure..It might have 77000..hard to tell...all I know is that it ran good...Like I said..I'm going to clean it up and put new rings in it. It's set up for manual trans, and smog. If you didn't want smog..You'd have to get diff manifolds, or whatever else to make it non smog.( Ca, Car)..........What's it worth after ???..Just something in the ballpark....
