Without looking up the code, displacement is embossed on the lower side of the block and in the lifter valley under the valley pan

Comes back as a 76 400 in one listing I looked at. But that's not to say others don't use same numbers. Appears to have a '75 casting date near dizzy that fits. Pontiac engines aren't my thing, what's mismatched?
