Has any one built a 396/402 with longer rods(6.385) or longer? is it worth while? I know a 454 + cubic inch motor is as cheap to do and the power benifits, just wondering if you would see more torque/horsepower from this motor

no one, no opinions

I've heard of people putting in 454 cranks in 396's to bring them to 434 cubes....is this what you're talking about?

No reason to build a longer rod 396 or 402 motor. the rod ratio is already favorable at 1.63 (same as a 427). THe other issue is pistons - other than custom, there are no options.
