Hey folks, I recently picked up a 1963 facon to fix up. I later discovered that the original 140 had been replaced. The intake manifold number is C9DE-6090-J engine block is C8DE 6015. I have gathered "I think" that this is a 1968 engine. It has five freezeplugs however I have heard that 5 plugs on later engines does not always mean it is a 200. Can any of you verify that this is a 1968 200.

Howdy Neil Wagner:

Given your casting codes were found on both 170 and 200 blocks and heads, it is difficult to say with absolute certainty, but, with 5 freeze plugs in this year, my bet is a 200.

Block C8DE have been found on 170- with three freeze plugs. C8DE-B on a 200 with 5 freeze plugs and dual bell housing bolt pattern in both.

The C9DE-J head is thought to be a 1969 only piece. It is the smaller head, similar in specs to the C5 & C6 heads, with a 1.5"carb hole, most likely a 52cc chamber for the 9:1 CR, and pre-hardened seats. 1969 is also the year of the transition to the 1.75" carb hole, larger volume, flat-top log and 62 cc chamber, "M" head was introduced.

Other than the freeze plugs, the 170 & 200 are indistinguishable on the outside. Inside, a 170 would have flat-top pistons and a bore of 3.5".

Adios, David
so wouldnt he be able to just stick a rod in one of the sparkplug holes and feel for the dish or not?
