Eagle 4" crank, Eagle 6.125" rods and there are several great pistons. Mahle makes great priced pistons and are a great product, Wiseco is the **** too.

IMO Diamond, Mahle , JE/SRP pistons
Eagle or callies crank
Callies compstar rods, they cost a little more than the Eagle rods but they are ready to install right out of the box and are lighter as well.

I would go with the Diamond pistons/ Eagle crank and Callies rods. Proven budget performer.

If your looking into a FI setup save yourself a grand and build a stock crank 370.

right now I'm building a 370 for my truck, stock polished, cryo'd, balanced crank, eagle rods and mahle pistons (only because i got a screaming deal on them) solid roller. i couldn't justify the extra $1000 for a big crank with my setup. it probably would have been a better way to go and would have made more down low, however down low isn't really what i'm after, and the bottle will make power low anyways.
