three dogs ive never had any issues with the 2.8 motor yes its sluggish and can struggle with the camper going up hills but you just drive within the capabilities of what you have having said that the engine is modified and most people ive been 4wding with that didnt know the car couldnt believe it was a 2.8 till the bonnet went up but i drove a mates 4.2 and another mates who has done the ls1 converstion and have to say the power of the ls1 impressed me but im old fashioned and cant shake the notion that 4wds should be diesels my young bloke is just finishing off his Ls1 converstion and keeps telling me thats the way to go just so confused guess i will do the ring around Monday get some prices and see where i stand from there
