Yes. Bore-scope up the drain plug can see the forge stamping on the rods on pistons, can't see a brand. Obvious cam chop on idle and while tuning. I'm not going to tear down the rotating assembly to get brands. If you're interested in a low mileage, 600 HP Lightning that cost 5-8k cheaper then equivalent trucks, come drive it. Pictures and words don't mean a damn thing. Tuned to perfection, runs like a stock Lightning until you push the pedal down.
