Thanks for linking that PDF, I will get to reading! And thanks for the reassurance. I am a bit leery to to do a wholesale change up of the carb setup since the car does run currently, but knowing that other people think it's way off too makes me feel better.

What kind of wideband are you running? Can you get on a chassis dyno?
I would definitely rather run 45s but I'm not going to spend the money soon to switch over. Thanks for backing up what I *think* the car should have before I spend the money to switch everything out. All the numbers I have currently were from a chassis dyno, including the wideband readouts. I have easy access to one and the car is not street legal at all so all the tuning will happen there.

EDIT: I will also add that this is 100% a racecar, I'm not worried about street mannerisms, or even being able to have an idle under 1k. It will see nothing but road course and the occasional autocross.
