60 & 66 inch inline 6 ??? (combustion chambers)

[David_L6]

Did either the 60 or 66 cubic inch inline 6 cylinder Mercs survive long enough to get the improved combustion chamber? The 4 cylinder Mark 58 survived as Merc 500 and got the new combustion chamber (what year?) and the 2 cylinder Mark 28 survived as the Merc 200 and got the improved combustion chamber (again, what year?). I don't think either of the sixes did though, did they?

Did ANY of the 10 cubic inch per cylinder engines survive to get the new chamber?

BTW, what is the correct term to describe that combustion chamber? All the racers down this way call it a "squish block".

The 66ci engine got to live thru 1962 which was the year the new combustion chamber was introduced. Alas, the 66 Ci engine did not recieve the new chamber however and lived it's final year as it always was.

I can't speak to the smaller engines. Mercury called the new chamber "The Powerdome Combustion Chamber"

I think David was refering to the other, older combustion chamber. The Powerdome isn't used on any of the race motors David likes so much.;)
