Here's the poop. Have a 1967 W111 250SE Coupe. Engine is tired. Bottom end seems fine (good compression), likely needs a head job and a maybe a MFI pump rebuild. Has a newer replacement auto tranny.

Question: Do the work and keep the original M129 2.5 motor OR drop in a super running M130 2.8 for a little more vroom?

The car's future is to be a shabby chic driver unashamed of bondo, not much hope of ever competing with Ralph Lauren at Pebble Beach. I figure the costs of the above scenarios will be similar, maybe less to drop in the M130.

Thanks for you input!
