Please forgive my ignorance, I am still new to the scene. I have checked the codes from the front/passenger side of the block but it still only narrows it down to two different engines.

The car is a 66 2 door hardtop automatic and I am not sure if the engine or the tranny are original.

F0327HO

From what I have found it seems to be a:

327 from 1965

or

350 from 1969

Are there any other indicators?

There's a number behind the driver side head. In my experience it's easier to identify an engine by this number. You will be able to identify it on http://www.mortec.com/ once you have that. They also have the head casting numbers which are located under the valve cover in between the rocker.

Yes, get the casting number and or casting date off the back of the block. Also, is theer a block VIN stamped near the application code? If not, I'd guess it's the 65 327. Most blocks after 1968 have the VIN stamped.

Does anyone has a photo of where the other number is located? It took me forever to find the first one because I had no idea it would be painted over. I has to go hunting with a bottle of acetone. :rolleyes:

The main reason I am asking is because I want to buy and install a new carb this weekend but I'm not sure what size to get. I read that if its a 327, I should go with a 500cfm and if it is a 350, I should get a 600cfm...does that sound right?

Do you you guys like the Edelbrock Performer?

If it's the 69 350 it should have some more numbers next to the ones you found--if it's the 65 327, it looks like a Vette engine that had a Powerglide behind it. Either way it doesn't like like the original piece.

UPDATE: The suffix "HO"; after a little more cleaning turned out to be "HC" which leads me to believe it is indeed a 1965 327 becase it is a 4barrel and the 1969 350 shows as a 2 barrel.
