The truck chassis might have trouble carrying the weight of an armoured body. I suggest you might want to box weld steel panels on the insides of the C-channels the way hotrod and custom off-road truck builders do.

Terry,
Good idea! I have to explore what weight savings I can get using mild steel. I want the correct thickness though. As this develops, need to see what engine can mate up and still fit. Not going to shoehorn a modern V8 with auto tranny! Will keep the straight 6 and intend to keep the same tranny. So many questions yet... <g>

Jim,
Sounds like a viable project. As a point of reference 3/8 thick mild steel weighs 0.06 lb. less per sq. ft. than stainless steel. The difference between mild steel & armour plate would likely be less. ( 10 to 15 Lb. weight saving on the whole machine ) Most Chevrolet 6 cylinder engines up to about 1961 will bolt up to the earlier transmission. I have several CMP lift truck conversions with newer engines. The advantage with a later engine is full pressure lubrication & insert bearings.

Thanks Jack! I fully expect this to be an educational experiance!
 When the original 216 threw a piston out the side of the block on my first road trip with the C15A, I was educated on the differences between a wartime "splash-oil" system and post war pressure systems. I found a 1954 230 block to put in. Did a full rebuild on the block and yes, it bolted right in. Seems the 54 and 55 230s used the water pump in the same location, so I had no clearance issues with the fan blades, but that was dumb luck... That was the only 230 block inthe local junk yard. I later learned how lucky I was when i read about the need to buy an adapter for the water pump if replacing the engine from a vintage Chev site. No idea at this point just what could be found and fitted inside the space of the Otter. While I want to try to get it street legal, I fully expect tot trailer it to events like I do the Humber Armoured Car. Thanks for the info on the steel weight. Not near as much a benefit as I had previously heard from "conventional wisdom"! Cheers, Jim
