67 barracuda fastback sport hardtop

Oh thank you. I’m happy with my barracuda either way. It’s a nice project car. I have another question. The originals came with a 273. The person I bough this from said it’s a 340. The cover says it’s a 340. But I’m not sure if it is. I’ve looked for the stamping but I haven’t found it. Can anyone tell if it is a 340. Any help would be appreciated. Thanks in advance.

I forgot which side it on but one side dr or pass has the code and the cid is at the end and the other side has the date and time it was made. Its on the block between the deck and pan. Ilrc its kinda in the middle of the block.
