408 Crankshaft

I used a forged eagle crank. Scat used to make the mopar performance. The problem with the cast crank is they're only good to 500 hp. With any performance build on a 408, you'll be close to that power level. I have a mild flat tappet hydraulic cam and untouched eddy heads. The motor thinks it's a big block but turns up like a small block. If you Google 408 build, you'll find ford guys having the same problem with cast crank 408 builds.
