RA III ?

[DaJudge]

Double check the block numbers 1968 400RA #9792506 . That same casting number is a RA IV if it is dated 69. The 96 heads = 19681/2 Ram Air II 400, round exh 2.11/1.77 71 cc's.

What are the two letter codes on the block below the passenger side head. See below for codes.

1964 35B,38S,44B,47S,45B,46G,50Q 421HO
1965 WG,WH,WJ,YH,YJ,YK 421HO

Skier,I believe RAII's RAIV's and 1970 RA III's had 4 bolt mains as well.
