I'm left feeling stupid! I'm looking for a k30 but.... i know it's gonna need more power I was thinking of building up the 454 or swapping in a newer engine like a vortec from a 99-06 silverado. But heres the tricky part I have no idea which vortec to get I was thinking the 6.0 which from my knowledge came factory with the option of a nv4500. Am I heading into the wrong direction? would I be better off building the 454? And is it possible to swap the np205 onto the nv4500?
