273 and 360 interchangeability?

He said in his original post that his LD4B intake wouldn't work because the bolt holes won't line up. Well, my bad, he has a 65 with a D4B. Heck, I don't know!
Sorry if I confused you. I made a typo earlier. I have the D4B intake because my 273 is a 65. The 360 I'm looking at is a LA motor.
