Im in two minds what to do with my merc w114
its a complete car so im tempted to put it back on the road and tidy a few bits and then drive it until winter then sell on with occasional use.

But on the other hand i want to lower it and stick a 5-6cyl turbo diesel engine in and use it often and probably keep it longer.

Can anyone think of a decent 5-6cyl td (no common rail stuff) ideally just mechanical pump old school type.
only ones i can think are
Old VW LT
Diesel out of W123 or similar merc
