My friend, who owns is own shop, socializes with one of the Top Fuel drivers when he's in town for the Route 66 Nationals. The driver brought this to my friend as a souvenir. It made several passes down the track while cranking out over 1,000 HP by itself. I had never held a top fuel piston assembly in my hand and we surprised how stout they are.

Yes, that's a LOT of weight swinging around at high RPMs.

The pin in rod cap is to keep the bearing from spinning!

I think it's much heavier duty than a modern diesel assembly.

Aluminum. The specific alloy varies depending on what is thought to work best.

Is CP Carrillo still the preferred vendor?
