Anyone know what engine, a K series head with ID number 39 (in casting between spark plugs 3 & 4), was fitted to ? No 39 is not listed in the Wiki. It is currently fitted to a 4K engine, I was looking at this afternoon, which has a few issues, one of which appears to be very high compression (about 180 - 190 PSI per cylinder). I'm suspecting it might be a 3K head on a 4K block. The engine runs on badly & is "dieseling". The engine is also fitted with a 3K dizzy. It has what looks like a carby without a fuel cut-off solenoid, so I suspect it might also be off a 3K.
Don't know the history of the engine mods, so it's a bit hard to make a call, without stripping it down & working through all of it.
Thanks !
