I am not sure of the driving habbit diferences or maybey the body styles but the most fuel efficient 350 i ever owned is sitting out on my lawn it gets an awesome 13 mpg ita a 98 2wd i have run a few 87 4x4s with 305s and never got worse than 19 in the city or highway my recent is a full rebuild its an 87 on a 79 1 ton frame true 1 ton dana 60 front 14 bolt full floater rear with an nv 4500 and im sorry off roaders but i swapped the 205 in favor of the 208 cause it dont blow apart when i put in 4wd at over 70 mph i get 21 city and 24 highway with a 1 ton and its the most versital vehical i have ever owned and uses no oil so dump on them all you want with over 569000 miles on my k3500 i will consider the 305 one of the best engines ever made my 350 dosent leave town it does have alot more power ill give it that but i dont see it worth the extra cost maybey cause i have a heavy foot but my 305 acomodates my 100 mph trips using no oil and getting 21 mpg doing it in a 1 ton will my 350 vortech gets me only 13 to 14 but i guell its all driving habbits
