[C10 - C90 Bill]

In my opinion, it is too big for a Medium Size truck. Not only do I believe you would have trouble fitting one in there, if even possible, those engines are very heavy and C-40 and C-50 front end specs would be too light for it. When available, GM only put 4-53's or V-6 Toro-Flow diesels in those trucks. Even C-70's and C-80's had nothing close to that big.

I admire your enthusiasm though.
