I would like to know what the value would be for a 7-2 power block for a 70? Would it be worth overhauling a power block or boring out a stock block .125 over? What are your opinions?

It all depends on what you are looking for..

Either will do the job... The Power Block will add a few HP and will increase the amount of $$$$ you put in the tank during the day.. Boring oversize even +.125" will add little to the power you already have available.. Increasing compression can be a good choice.. If you really want to go big, think 10" stroke and 7 1/2" Pistons, New Better cam, etc, etc..
