Re: GM "hot fire" coil packs
He is definitely a Tool,
Flex fuel 5.3L (L59) engines have bigger injectors because E85 requires more fuel volume compared to regular gasoline, Powerwise they are rated the same as run-of-the-mil LM7's.
The only "HO" version of the 5.3L is a L33 all aluminum engine (310-315 hp) depending on the day of the week & how many beers you have had.
