    What do stock 5.3's make at the wheels.....in reality...not using the 30% loss through trhe driveline method (math method)....and what does the 6.0L make at the wheels...just wondering about the stock numbers for a comparison...

    If anyone knows where around the 15's they run stock, or small modded like free mods...that'd be a BIG help......just comparing numbers from the mpfi kit to these....later

    30% driveline loss is too much anyway,IMO. Probably closer to 15-20%. Most stock 5.3's will put down somewhere in the 230-240rwhp range.
