depending on your power goals , but up to 1000 hp , simple stock crank stock displacement or callies 4.00 crank (4.100 and larger is not suggested because the sleeve length on the stock ls3 is only 5.6" and with longer then a 4" stroke crank the oil will usually come out of the sleeve at the bottom of the stroke causing oil consumption issues usually), manley/k1 rods, and nice wiseco pistons (4.065" bore), would definitely suffice

Same question, what are your power goals? Depending, you'd probably be fine with stock crank, stock rods, and forged pistons (not sure what kind of pistons the LS3 has stock).
