Buying a 360 engine , have a couple questions ???

The trans that's in my car is a 727 . And the idea of the balanced flexplate is a great idea , which im gonna deff consider when I get the motor , and check with everything . Magnum motor is also I good idea too. I'm buying this 360 from a buddy getting a good deal and i trust him , it's also got aluminum heads on it , I like the weight savings , and a little bit of work . Nothing to crazy .
