I'm in the process of doing repainting and detailing under the hood. The last owner told me it was rebuilt but did not have any details. When I took off the valve covers it was soo clean in there you could eat off it.. Anyway, the heads have these numbers on it

2F29 on one end which I think is the casting number and 302 on the other. Are these 302 heads?? I may be looking in the wrong place for the casting number..
Thanks!!!

Picture below;

 

yes its a 302 head you got, not nessarily a 302 block, but inside the head, they casted the appropriate engine size number into the head imo for better identification for replacement or for the engine assembelers.

 

Thats what I thought. Not sure about the block, I know the casting number is up on the underside near the starter. Which with the starter there, I may not be able to see. Is there another way to verify if its a 302 or a 289 block?

 

Here is a good site for casting numbers http://raceabilene.com/kelly/hotrod/engine3.html

Thanks.. Now that I know it has 302 heads, I have to try and find out if its a 302 or a 289.. I know there is a casting number up under weere the starter is but, is there any other way I can verify if its a 289 or a 302??

 

2f26 is the date code for the heads, the date code for the block is stamped on a flat boss where the block and head meet above the fuel pump.

 

What does that date code come out to be?? By the way, its 2F29

 

Bump

From what I could find (which is not much) this date code 2F29 could mean "June 29, 1972"...........

 

Which can probably mean you have a 72 302 in your car. It could be a mustang 302 or a truck or van 302.

 

I would read the date that way too but am not completly sure all my books gave me were examples of how read them from the 60s. From what i can find out chamber sizes on 302 heads didnt get larger until 76 or so so those ought to give you pretty good compression. If you find a date code on the block thats later than 68 its a 302 block.
