Stock 318. Aftermarket pistons but still in the whole? But they are replacing the rods with ones longer to zero deck it? WTF are they thinking. DV polished the beams on that stock rod because he could and it didn't cost anything but time. It will make the rod stronger but it won't increase the performance. He could recondition the rod and add a new set of ARP bolts and it would be good to 400+ HP. Oh, and I didn't know that a larger bore increases compression. WTF
