I bought castings only on black friday 2020, with shipping was under $450 for the set. I had my engine builder put good components in them for another few hundred. I doubt the car would run any better with Edelbrocks for twice the money or more. Its a 360 with stock crank and rods with Icon...

I am not under the impression a given A/F will get me away from adjusting my dial with the weather. I am asking to see if and at what A/F people have seen the changes with weather effect ET less. Thanks for the calculator suggestions, I really appreciate it.

I stand corrected, I should have said there are many reputable folks that believe jetting is beneficial at different altitudes.

Density altitude will change 1,000 to 1,500 feet throughout a day of racing for me just about everyday. So you are saying Warren Johnson said proper jetting at a mile high is the same jetting as sea level? Do you think he was compensating in other ways? I don't think you can find any...

Most serious bracket racers I talk to will rejet at least a few times a year and some much more often. I have and would again trade a tenth or two for more consistent.

That doesn't mean I think it is or should be flat.

What makes you think I think it should be flat? The trajectory example was not intended convey the desire for a flat for A/F curve, but to make the weather changes less extreme making them easier to predict and more forgiving if you predict incorrectly.

Would you not want to have a tune up that made the car the most consistent? Is it possible AFR is a key factor in a consistent set up that changes less with weather making the car easier and more predictable to dial? I am trying to flatten the trajectory similar to predicting vertical hold...

Yah thats my whole point. Trying to figure out if anyone has noticed a base AFR reading that varies the ET least with given weather changes on an average day.

I would agree with it not being possible all the time especially with only getting one or two time trials, but surely those that track have some idea about what it is and how consistent the car is that day.

For those that track it, what is your experience as to what air fuel ratio you have experienced the best consistency when bracket racing.

The time would be very similar. With a highspeed machining center you can make 20 or more passes with a proper constant chip load that wont wear the tool as quickly, chatter or rub like a large cutter in the same amount of time with more precision and adjustability. In addition to the...

Coming from a tool and die making environment making plastic injection molds and precision manufacturing fixtures for 25 years, machining an arc like this with a single pass with specific sized tool is not the way to it. A single pass with a large cutter will typically result in a poor finish...
