Thanks for the offer. If I do replace internals it will be with new parts not used tho. This isnt a budget motor build,if the stock parts wont handle another 100-150 HP/torque I will buy parts that will. I guess Im just tryin to see if anyone has found the limits of the stock bottom end or is still pushing one hard and having good luck on cast pistons.
I have been a 5.0 and 2.3t guy my whole life so this will be my first time playin with a 385 motor.
