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
