As for manifolds, I have found nothing yet. I only checked pierce and twm though.
Ignition, I will be going electromotive, distributorless... That way I can custom wire and rid myself of anything that I do or do not want. Not to mention my own advance curves.
My original plan was to get a set of manifold gaskets from ford and fabricate my own, then do a set of tubes to link to a set of generic webber manifold plates...then weld them up, and ceramicoat them all pretty.
If I can find something prefabbed though, I may go with it. I did see a set of throttle bodies for audi straight fives....two sets of those and I would be good to go. Just need adapters...well and everything else to run them!
Again, cubic dollars...I have time...and no motor or car even...
