I have 351C-4V Closed Chambers heads!

My motor aint the original so i did some investigation of what motor i really have.
The heads have #4 on the left corner so i did know that it was 4V-heads but not if it was open or closed chambers.

I started to meassure the deck height to asure me about that it is a Cevelamd and not a 351M or 400.

Meassured several times and got 23,4 cm/9.2" each time. :)

Took pictures of the backside of the motor and found a chassi number for the car the motor was originally in OF....

Then i tried to see what casting number it was behind the starter, could only read DOAE,,,,

Pulled the valve covers to see the date code 9J9! :) :)

9J9 means 1969 sept 9:th, and is so called closed Chambers or Quench Heads.
Compression ratio is 11.0:1.
