Big block Ercole?

Just saw a post of one of the 500 singles trucks (Ercole?) on Facebook and got to thinking:  How hard would it be to take, say, and 850T3 and put a bed and two rear wheels on it?

I've thought about building a Loopframe based Ercole type vehicle. An extra transmission behind the standard 4 spd. for more ratios and reverse, truck rear end. But, I have enough projects going on, so a Loop truck is just a dream...
