First 1967 383 installed in a Barracuda

Not that it applies to your thread, but I have a VIN for a 67 Barracuda that is a 383-2 Barrel.
Not an H, but a G.
So who knows what was going on.
So this is a BH29G at the start of the VIN? Do you have a pic of this motor in the car and the VIN? Would be interesting to see that.
