Hi Aaron,

                When an engine is that olde, all sorts of mods or refurbs could have been carried out in the intervening years, with dished pistons, & maybe a flat head being fitted.

However, if the engine is original, it could be a 4KU engine, which did have dished pistons as standard, & produced a bit more HP, than the more common 4KC engine. 

4K-C   43 kW,      4K-U   55 kW.

The 4KU is not commonly found now, so if you have got an original 4KU engine, hold onto it.

I've run one in my KE30 for years now, & it has been a great engine.

You can check out the difference of all the 4K engines at this link.


Cheers Banjo
