46 GMC - great input. I wasn't being clear, but for a vehicle that's driven 3-4 times/month was wondering if the LS would be less troublesome over the long run. Haven't done much research yet(that's the purpose of the post) but hoping there is a "hot rod" chip/setting so don't have to fuss with all the modern emission kit.
Thanks
