Directly to the rear of that number reads "CON2 ?H25" I presume that this is the engine code, but the letter preceeding the "H" is obscured by the dipstick. From my references any 66 engine with a "H" is a 292cid (ie. UH). But the casting number reference shows 230-250cid.
It is a 3-speed of the tree if that helps?
thanks

There are stamped numbers down by the motors mount as mentioned in my earlier post. Are those the ones I should be looking for???
thanks

Official title reads 107K and everything under the hood appears to be bone stock. The VIN sequence number is 100385, which rules out a late model 66, correct??
Sounds like someone changed my engine.... | | |

The easy way to tell a 292 is the right motor mount. On a 292 it will be near the front of the block, on a 250/230/194 it will be directly opposite the left mount, about the center of the block.

TIA

F=Flint engine plant, 1223= December 23, and I'm 99.9% certain A= 1960. One of the last motors built before the X-mas break 1960, the 1961 models were of course already in the showrooms.
