Are there any crankshaft upgrades for a 1995 ford f150 inline 6 300? It's carbed with a upgraded cam.

 

Do you need an upgraded crank? I've never personally seen anyone ever break a 300 cast crank. Unless you plan to spend a lot of time north of 6,000 rpms your stock crank should be fine.

But if you are dead set on a upgrade you will have to find a stock 65- mid 70's 300 HD Steel crank. These are getting hard to find. And when you do find them they aren't cheap. There are no aftermarket cranks for the 300.

I would worry more about improving the rods. Adding some ARP rod bolts is a better use of your money.
