      Hey Tom,
      Great to see the Goat coming along!!
      Re: 76 400- The reason you need an adapter for that block is the factory only tapped, and in some cases only cast the bosses for, the three bolt pattern.
      All 455's have the 5 motor mount bolt pattern on the side. They fit early and late frames.
      AllFaith- sorry this is late, but as someone stated, Yes the 69 400 engine mounts will allow you to bolt a 455 into your chassis. In 1970 the A-body cars got a seperate 455 engine/frame mount combo. When I put the 455 in my 68 LeMans, I just used the stock 350 frame mounts and the 350/400 engine mounts.
      Have fun!
