5.3 with a well tuned carb knocking down economy as good as a lt1 still needs a cowl hood to run an air cleaner. Otherwise, odd comparrison. Great economy can be had from a carb, but efi as mentioned can have better tuning ability the is irrelevant to some and important to others.

Re: LT1 EFI vs LSx 5.3 carb
Good point about the hood and cleaner. Not sure how tall the carb lsx setups are. Carb can get mileage but it would take a good bit of time to do it and still dont have the greatest control of fuel and timing but not sure how the lsx timing boxes work. Zone89 could tell. Can it control timing versus rpm vs map like in the efi systems?

Re: LT1 EFI vs LSx 5.3 carb
I will be swapping but i have th400 trans so it helps on highway. 80 would be 2800 rpm by the tire size but my converter would likely be slippin a tad higher and id be on verge of boost lol
This new combo doesnt like tall gears. Turbos like load but not this much. 3.08 or 3.31 may be in order
Sorry for the threadjack
