BBC Trucks
 

I am entertaining the idea of putting a big block in my 1990 2500 Chevy truck. If I could find an old wrecked ss454 truck it should be relatively simple. Mine is currently a 350, I have no problems with the mechanical end, I am only concerned with the electronic contolled side of things. Is anyone firmiliar with this swap?
Thanks,
Bill

dont worry about finding a 454SS there the same motor taht came in all the 3/4 and 1 ton trucks. just look for the a truck with either a T-400 or a manual trans.. they had the same ECM . which would be reral close to pug and play with your 350 harness.... or you could swap in one with a 4l80 but youll need the harness with that one as well:)
