i am prob in the minority but i prefer the inline six. i have drove exclusivly 63 to 66 trucks for years. the sixes are easier for me to tune work on and you have way more room to do it. everyone wants a v8 so 6 parts aren't too bad price wise. some of the internals will interchange with the v8's. only one head gasket, one valve cover gasket, quicker valve adjustment, easier to change fuel pump, easier to reach dist, exuast easier because more room, spark plugs easier to get to, and a lot of the sixes haven't been beat like a scalded dog like the 8's.
about the only disadvantage is the manifolds tend to warp because the are long. because these trucks are work trucks don't expect them to go too fast. that will add lots of life to your truck. the milage might not be as bad as you think. my trucks don't get that much worse than a lot of newer ones. but the top speed is something different so don't expect that. trust me you will be able to buy a tanker truck full of gas with all the money you save on mechanic bills and high parts. i could type a list from here to the moon of crap parts that are unbelievably high on new trucks and take high dollar hourly wages at the shop. once you get spoiled you're mouth will drop when friends tell you what their repair bill was. yes it happens on newer trucks a lot. yours will be running down the road for pennies.
now a full restoration is another story. have i sold on the idea yet? but don't shell out to much, a good deal can still be found. i have drug them in for free, paid $50, $75, $200 so don't be afraid to look for cheap. the most i paid for a 62 2 ton was $1000.
