Now we need to fab up the head pipes. We're using 273 manifolds from a 65 Dart and I'm hoping someone has detailed pictures of their own comparable setup. Mostly I'm interested in routing passed the transmission.

I think on the drivers side, It's going to come almost straight back (slightly down and inboard), then do a quick "Z" and level off again, on the the pass, it looks like a quick turn back, then a double "Z" and leveling off again.

A big question I have is how close, is too close to thins like transmission lines, oil filter etc?

Any tips would be greatly appreciated.
