Does some one know if the stove pipes for 350 and 402 B.B. are different.Recently got a stove pipe"tube" but it seems that it does not quite fit the configuration.of my heat shield.Thanks for any help....

Yes, they are different. The BB pipe is much longer overall. Here's a couple of pics... These are of the BB of course. The pipe has a long way to go to get down to the manifold.

Sorry, no pics of the 350.

Wow,

The A.I.R. system really covered those California 402's. You don't see many all intact.
