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.
