Robert, It's not actually my engine, but what an engine upgrade it would be, I need to measure engine mount locations and length back from the gearbox position, apparently the carrier box will bolt straight on. The idea would be to check this engine would not foul the division plate with the radiator removed. With a carrier wooden blanking plate in it's normal position and a radiator located further back maybe above the engine with an electric cooling fan. All engine covers in place it would look like a standard carrier.
Just an idea as it would still sound like a flathead (part of the carrier appeal!)
kev.
