Trying to find any information on my car and 340 engine

Thanks for the reply.
The Block is a 70 with a different vin.
The heads are 69 and other items are dated 69.
The trans is correct vin number for the car.
Fender tag is there and I have decoded it, has many options but someone removed the A/C parts.
That breather cap is wrong for a 340 valve cover
