318 doesn't have to be “ rowdy” to make 400.
The 318 in my old car made 477 with iron heads on pump gas.
248/248 solid cam.
I “ detuned” it ran a 231/238 solid cam, and it still ran mid 11’s at 3400 pounds not leaning on it. Shifted at 6k.
Some very slick machine work, but 10.4 compression, knockoff airgap intake and cheap 1 5/8 no name headers.
