Thanks a lot Paul for bringing some light in the manifold darkness.
Do you think the manifold was bored ?
Ok, maybe that was the reason for the crack...
Even if I would find a 67 manifold, it will be a difficult to
reproduce the same borings,
two different manifolds won't work.
I tend to use the 'smaller' outlet manifolds,
what do you think,
how much would they affect the engine characteristics ?
