Top fuel cam and crank came to the shop

[Oldmanmopar]

Here is a Hemi fuel cam and crank The cams are sitting next to a factory cam, Check out the heavy metal in the crank. My son just did another a big block crank . The trick is to cut the counter weights .150 and move the weight to the center. He is doing a 440 crank which will get the same heavy metal to move the weight into the center of the mass. I can get a picture of the crank tomorrow next to a stock crank. Big difference in diameter

He does alot of Subaru and EVO Performance machine work for Race shops on the East coast. E.A.G. send him work also. What I see a lot is 6.7 Diesel heads. Damaged from seats fallen out.

That's cool, goes to show they're all just piston engines at the end of the day. FWIW I'd take an Evo over a Subie any day at least they have proper iron blocks and don't eat head gaskets like a fat kid at a candy store.

I watched an interview on DragBoss Garage with Darin Morgan(?) and he explained how Pro Stock engines have the crank counterweights cut down as much as possible and heavy metal added just to keep the rotating inertia as low as possible along with windage, pretty important at 10,000+ RPM. I thought the cam cores for a Fuel engine would be bigger than that but I guess they don't need to spin astronomic RPM when the fuel is basically a high explosive.
