yet another 413 question

I found a 413 motor with a 74 440 crank and balancer he wants 300 for it it has no ring ledge and no cracks this is just a short block no heads or intake it also has a 3 bolt cam I have tried to find it in my direct connection book and my mopar performance book ( its old but been good up to this point). what I need to know is would this be a decent motor I dont know what it came from or what year it is I just cant afford to rebuild my 383 right now and thought this would be a good option.

thanks for your thoughts
