that out of a 69 340? my valiant ran 14.2's all day long with a stock 79 360 long block with a performer intake and 600 holley being choked dowm by 273 manifolds. 3.55 gear too..
That's why I have long advocated for the 360. It got a bad reputation due to being released at the beginning of the smog era and not having a performance option until 1974. I remember conversations in the early 1980s with people degrading the 360 as worthless. I knew they were mistaken...
