... i doubt it would out perform the 750 up top......
also it certainly is
not the best overall performer.... if it was-- it would still be on the truck.
the only tuning done was on the idle circuit.. which was way too rich no matter what was done...
one can tune the thing all day long and eventually--i suppose--you will get close to acceptable "around town performance" with the d/p.... problem is the main jets are just too big in stock form for what is actually a relatively mild 5.3...
if i could knock 1000 lbs off my truck and switch to a ~3200 stall the d/p would be my carb choice no doubt.
