Dave generally when I do a COE I prefer to put the engine back behind the cab just so it is easier to work on if you have to.
"BUT" on this project I am going to put the engine up front as low as I can because I want to shorten it to PU style and I want the wheelbase fairly short.
but if I were going to have a longer WB or a flat bed I would move the engine behind the cab. Ron...
