Thanks for that and no doubt the iron is way heavy and in fact, I'm in the middle of a minor teardown to fix an intake leak and get the carb redone, so I guess I need to be more specific here... ok, so when we look at the performance side, what I want to know is do aftermarket replacement alu's make a dramatic difference in mpg and/or drive-ability? Positive or negative impacts?
When I say after-market replacement I'm talking about something for a daily-use work truck, stock 350, no need for overwhelming power here, something like the Weiand 8000 w/egr, spreadbore for Q-jet. By the way, this will also be my tow-vehicle too for boat, car-hauler, etc., and I'm looking for longevity, dependability, and not getting killed too badly on the gas mileage--- compared to the stock iron that is.
