Basically if your thinking of rebuilding a motor, you need to ask yourself what kind of horsepower you want to make. The 1g rod, 2g piston combo is said to be good up to 450whp, requires a little bit of machining but alot of people use this combo because it is less expensive. I am currently running Ross forged pistons on 1g rods and I am happy with it. No machining necessary, just a pin fitting by the machine shop on the 1g rod, forged piston combo. As far as main studs go, again how much power are u wanting to make, like the rest of them said, they are not needed but if you plan on making over 500 hp go for it.
