A lot of good info above. I have an 70 olds 442 with a 455. I am pretty sure the 455 gets most of its added cubes by being a tall block 350 and bigger bore. Intakes will not interchange as the 455 intake is wider. Comparing the physical size of the 455 to my bbc in my 67, the 455 is like picking up a small block. I like both engines with the 455 having 500 ft lbs I think at around 3300 rpm. My bbc 402 is no slouch either with gobbs of low end also.

The 455 needed an OD so I added a 700r4 ----- now a real 442.
The 402 needed an OD also and got a 700r4 ----- nice.

just rambling.....
