1970 Dart Swinger FINALLY UNDERWAY

I believe it's most likely an RB 383, it's a 1970 block from what I understand the 383s were on the RB block at that point. Should I got for it? Going to go take a look at the engine tomorrow, it would save me a lot of money since it already has all the machine work done, is complete intake to oil pan with gasket matched heads and I just have to put it together.
