Head ? I should know
I would know this if 60yrs ago, anyway my boy got a CList $75 Late 239.
It was suppose to be froze up, but not just couple stuck valves. I tore
into it Sat nice and clean, valves are Ford no ridge bore measures std
with .0035 wear no cracks anywhere. question I know my 8RTs and 8BA's
but whats a ECM 6030 D Ford script heads? Is this Foreign or Merc. something.
I have not measured the stroke yet. It has truck pan -fat belts- late bell
housing. Also the seller has a crate of new Ford water pumps with double
pulleys??? never seen double pulleys on pumps or ECM heads maybe this is
industrial or something. pumps have Ford scripts also..
I think I'm going back for some pumps $20 and they are truck pumps.
any ideas sam

ECM sounds like a late Merc head, same era as the EAB Ford. I don't have any catalog to confirm. Sounds like a score overall, if it's a Merc engine, but Merc heads are near worthless on anything else.

Merc heads have larger combustion chambers than Fords, putting Merc heads on a Ford 239 lowers the compression ratio. On a Merc engine, they result in the same C.R. as a Ford 239 with Ford heads. Putting Ford heads on a Merc engine boosts C. R.
8CM is the Merc series corresponding to the 8BA ('48 - '50). ECM is the '52-'53 Merc 255 series corresponding to the EAB Fords, as far as I know.
