Best Internals???
Guys have made BIG power on the compstar rods, Diamond pistons, stock crank
REALLY BIG power usually requires something like Oliver billet rods, Wiseco (Turbo) pistons, and a crank like (Sonny Bryant, Callies magnum XL, Callies Dragonslayer)
The Lunati Pro-billet are nice.
The GRP aluminum's that are in Fireball's BAD *** Virginia speed motor are only good for so many runs as I understand it. All the 1500rwhp and up guys usually use the Aluminum ones

Good internals for 1000hp IMO would be:
Compstar/Dragonslayer Crank
Callies H beam Rods
Diamond/JE/Wiseco Pistons
But i have heard of guys pushing thoes parts ALOT farther!
Also, if you are doing a budget build try using the factory crankshaft. If you are doing a budget build you might want to look in "The Real Price of FI"
Goodluck.
when we tore down the motor over the winter, there was zero evidence of crank flex even at ~1400 FWHP
