Re: Whats your impression of a 5.3L LS motor in these trucks?
Power and milage aren't mutually exclusive.The better the power means a more efficient engine(generally).It's using that power(heavy right foot) that makes the milage drop.The 5.3 may not do any better than the 6.0 as far as milage when driven the sams.The 6 cyl in these trucks seldom gets much if any better milage than the 350 and even some BB.The EFI engines will have better driveability and should do better on the hiway than a carbed engine,but the 6.0 may have better milage heavily loaded or towing than the 5.3.There are just a lot of variables,the biggest being how you drive.
