What needs to be done to beef up internals?
Wanting to make the overall engine on the 3.7l stronger to handle more power. I keep hearing make the front end stronger. Is this any particular part of the engine? I was already looking into stronger pistons and camshaft but know I'll need to do upgrade more. Any ideas or suggestions?

There isn't much for the 3.7 V6, it's not a boosted engine...
It already has a forged steel crankshaft, connecting rods, and a few other small parts.
The new valvetrain uses the new "megacap", which is, a front cam bearing cap on each bank
that manages oil flow to both variable cam-timing sprockets and down through the four hollow
camshafts to the cam journals and the rest of the valvetrain. This is a way better design than
the 4.0's valvetrain. Each hardened tappet has a very slight crown in the surface, about 15
microns from side to side, to work better against the surface and metallurgy of the drilled-out
hollow camshaft’s lobes.
Deep sump oil pan.
The ProCharger guys took a bone stock 3.7, put only 8 lbs of boost in it, and made 427 hp to the wheels,
which translates to almost 500hp at the crank.
The 3.7's not a dud...
