Hello All,

My name is Tjesse and I am form the Netherlands. I own an '65 Coupe de Ville and I have had too much ignition-failure latley so I'm upgrading it.
I bought this very nice HEI that was fitted on a 1978 425 engine.
Before I tear down my engine, can anyone tell me if it fits???
If it doesn't, then I'll make it fit but so I'll know what to expect ;-)
