I mean no disrespect but am a little perplexed. I would think there would have to be some firewall and floor modification to fit this engine in your truck

http://www.curbsideclassic.com/blog...5-hp-at-2400-rpm-630-ft-lbs-at-1600-rpm/would be very difficult. I am no body man or expert welder by any means but wouldn't you have to stretch the frame and the hood amoung other things? Other wise the back half of the engine would be in the cab.
Just asking, maybe I am misunderstanding the whole build.
