Default 1975 Vin code "E" engine??

What am I missing here?

Hemming's 1975 Formula

The car is obviously restored and lightly modified (with a myriad of extra badging), but the purported vin has an engine code of "E" - I cannot find that engine code any where...
Did someone misread the vin (then have the door sticker misprinted to boot)??

75 had catalytic converter, may have dual outlets at back though.

You could get a 1975 Formula 350 with a 4-barrel, I had one. It had dual exhaust out the back, but only one catalytic converter. I don't remember what the VIN was.

with 1975 they all had “Y” pipes to the cat, then the “dual” exhaust would split there after.

Thanks guys!
I knew that the 350-4bbl returned for 1975 (then iirc it was dropped again for 1976, and came back for 1977 - the P350’s final year).
It looks like both sources I have here suggest that the 350-4bbl was an “H” ??
