One item that has been eating my lunch for me is a better distributor. I've been hunting a 75 for a few weeks and just now was told it shipped. Ok I've heard it before so I'm not going to hold my breath waiting. I was digging through all the posts of altered distributor advance but none were very clear of how this was done or on which particular model or year of distributor. I found a very good pic in RallyBobs turbo postings that show a lower bracket that none of the early styles had. It was this bracket that was used to limit the advance. I have been looking for a way to get there in a few steps and didn't really find too much. Before I go back into fall back and punt mode I'll try an odd idea or two on one that I already consider not the best and then I'll hold my breath and hope it really did ship this time.
