Need set of (8) 340 .060 over 4.100 used pistons CHEAP!!

Here's the deal I have a 72 340 block that is already at .060 over and has a slight ridge on the top of cylinder walls. I have a crank, rods, bearings , push rods etc etc. My 12 year old son asked me about 340 block and parts sitting in the corner and asked if we could build the engine together and start it up. Well after thinking about it, I am not going to pass the chance up to do this with him. I really only need a set of pistons and a cam and lifters for this project. If any one out there has a old set of .060 over 340 pistons they are not going to use and would like to sell them, and a used cam & lifters set up please contact me. I really dont want to but new parts but I will if I have to. Thanks
