I'm getting some work done on the 572 BBC that I printed out. I'm using a printed distributor that has bigger holes and I can't drill out the holes for fear of breaking out the outer wall so the holes are not very deep. I think I may epoxy the plug wires in the distributor first and see if I can route them to the block without them breaking out. The air cleaner is just setting on the carb. I haven't decided if I'll leave it black, painted it red, or chrome it.
