Rebuilt 1973 340 motor

The guy I got the car from didn't have any info except who built it. I heard it run before I bought it and even took a video of it running before I pulled it. Unfortunately the video is too long for me to upload on here or to email it so if you are not local to me you won't be able to see it. Thanks for the suggestions but I am not tearing apart a good running motor just to see what is in it. It's your run of the mill bone stock 340 with a cast crank and J heads with a mild cam and a couple of races on it. No street miles. I over estimated the mileage just to be on the safe side. If any body is interested send me a pm if not if you have any other helpful hints send a pm. Some of the suggestions/ opinions are not helping me sell it either. I think it is priced pretty fairly compared to some of the other junk motors that don't run or need to be rebuilt I have seen out there. I don't think you can build a 340 for this price. You are not going to break land speed records with this motor but it will be a nice street motor in a Dart.

Thanks again to all who responded
