I have boxes of nitro pipes but don't know what motors they match with. Is there a common inlet dia. To engine size? Like pipe inlet 7/8 is for a .67 engine.

Generally, 1/2" I/D = 21's, 5/8" = 45's, 3/4" = 67's and up.

Thank you Terry,
That is what I was looking for. Being stuck inside I have time to root through boxes of unwanted stuff to post.
