You could do stock rod/pistons. The only downside is the very low stock 7.8:1 compression pistons. If you do pistons, you will need to make sure you get pistons that will work with stock rods, unless you do aftermarket rods also. You will probably want some thing like a DSMLink or an AEM EMS, to get rid of all the random misfire errors that will usually happen when you put a 1G motor in a 2G.
