Thanks for the interest. This stuff is fun to me as well.....
- I doubt the poll for "people's choice upgrades" will happen. Limited supplies, time, as well as the cost kind of crimps that. I'm not sponsored...LOL
- Gears will happen, searching now to find a good set of 3.55's or higher. Nothing costly, 741 case and open is fine.
- Headers maybe. I have a set I saved from the scrap yard... old try-Y's... LOL
- I always like to see what each item does separately, however, that too is time and cost (about 60 bucks a trip to the track). So, I have to trust my "seat of the pants" feel if it made progress or not on some items.
