thanks for the recommendations
Thanks for the recommendations.
I eventually got a rebuilt from Ford.
However, they dropped the first one and cracked the Block somewhere in Ga.
And the did not have any short blocks lying around so they had to build a new shortblock in Detroit and put the new(er) heads on it.
So, the engine is in and I got it back today!
Did a test drive with the Mechanic in the passenger seat.
Still feel a little vibration at idle.
He said they could not get rid of the virbation and they did not see any indication of any problem to cause the vibration.
Hopefully this is end of any cooling problem... if they eventually got that fixed in the new heads.
Anyway, I am back on the road!
