I have a 67 289 and the pipe just pushes into to manifold. Pretty low tech.Beside automatic choke cover, there is hot air pipe, which should be connected here. I don't see any thread in this old manifold, so how this hot air pipe for choke should be connected ?
I have searched CjPony and found out that COMP timing chain is similar, is it good choice ?
We used COMP products in the hobby stocks and liked them.
