if i go the truck ls1 i will just use the 4.8 i have and then latter get a 408 block to replace the 4.8 block. right now i just need power and good mileage. i already know that the 6.0 doesn&#39;t get great mileage, my grandpa&#39;s truck never gets better than 16 on the highway. even my 350 could pull that kind of mileage, not as much power but still. the 4.8 gets 18-22 mpg on the highway. but if anyone has any more suggestions keep them coming, i really do appreciate all the impute and advice, since i still haven&#39;t made any set decisions, if anyone has a suggestion on another engine to use you may be able to change my mind.

i got my aeroforce gauge yesterday and i was using the MPG function... my truck a 5.3, cam, headers, ORY, and a nelson tune, i was gettin roughly 20-25 mpg depending on speed, wind, how flat the road was... i could hold a steady 23 mpg... i dont know what kind of milage you could get out of a 4.8... but thats something to think about
