5.3 GM Engine differences .... Curious to see if there is much difference power wise between the L59 flex fuel engine than the LM7/LM4. Based on the fact the flex fuel injectors handle E85? This will be after a tune and came pkg. Have a friend looking at doing a conversion and he is looking at the Lm7/Lm4 & L59....
