Re: 305 v8 or 250 I6 for better mpg

same milage with my 250 & 3 on the tree11-15 mpg best . i think a sm465 and 3.08,s would be worth tryin. you,ll need 1 st gear to pull out in for sure especially if your loaded my truck dont like it a speeds of 65 mph or more with the 3.73,s . i think a nv4500 and 3.73,s would be nice too .
