Internal or External balance 408???

What's your total build cost, $6,000?

Ha! I have that much in PARTS for the long block. No headers, torque converter, carb or machining costs...

What brand pistons do you have and are the heavy ?

They are Icon 745 pistons. They weigh 635 grams with the pins. I don't know how this compares to other forged stroker pistons.
