The HO and Ram Air 1 motors had D port heads and the Ram Air II motor had round port heads with the standard size intake port in `68.In` 69 the Ram Air IV motor was introduced with round port exhaust like the Ram Air II but with a taller intake port had the same cam as the Ram Air II but had 1.65 rockers.The 400 HO was called a Ram Air III in `69 and `70. So,no the Ram Air IV and HO motors do not have virtually the same specs.
