So i've got a 79 f250 Ranger Lariat Camper Special edition i'm in process of restoring. has factory dana 60s front and rear 3.55 gears, 4 speed right now has a 460 in it but have the original 400. I've got some options i''m trying to figure out enginewise. I have a 460 block, the original 400 block and also a 351 windsor block. in the end i plan on having 4.10 gears, a c6 auto and whichever engine i end up building running 35 inch tires. What would you guys do? I want it to run pretty hard and if i do a windsor it will be a stroker as well. Also want to be able to run 10mpg at least haha when normally driving that is. im getting 7 with the 460 im running RN
