My 340 Score of a lifetime!

So yesterday I was browsing the FB marketplace and looking at cars and engines. I came across a post listed as Dodge 340 Motor. It only had one picture so I asked the seller if he could post a pic of the Casting numbers. He told me he would in the morning. Well this morning he replied and it was a 340! I told him I would be on my way and fueled up the truck and drove to San Diego, 2 1/2 hours from me. Once I got their I met the seller. He was and older man and told me that his son wanted to build it back in the day for a 68 dart he had but went to collage and no longer had the car and it was taking up space in his shed. We loaded it up and I handed him $100. Yes that's correct $100. He had it listed for that and I even asked him if the price was correct on the listing, he said yes and the stands included.
It is a 1971 cast year with a set of X heads on it, which I did not know until I saw it in person. I disassembled it and Pistons look to be .030 over and might only need .010 more.

Talk about a deal! I always wanted a 340 but was crushed by the prices they go for. I know the 360 is bigger and I have 2 of them I was going to build for my 73 Valiant and my 75 Dart Sport. Now the Dart sport is going to get a 340!

Here are some pics of the motor. The Air gap intake makes up for the whole thing!

Nice find, but have the heads checked up, looks like a head gasket may of been blown out.
