My 78's are original...including paint! One even has all the original pollution equipment, in working order. I haven't done much to them in the last decade so they're going to need a major cleaning and polishing, and painting of some external engine components, might even do the blocks. Hopefully I'll get to them this summer, if not next summer it will be.
Back on topic, the peice manifold in my 80 LE looks alot better, and probably preforms much better as well.
