2000 chev 3500 srw 4dr 4x4 with 4:10 gears what kind of fuel mileage would i get? What would a 350 engine set up the same get? It would be 80% daily driver and rest towing 2000 lbs - 11000 which motor should i get?

 

The 454s usually get between 5 to 10 mpg but will tow any thing you can hook to them, the 350 will pull pretty well and get better mpg, what are you pulling, boat? trailer?
