"ideal for track day builds" with an iron block? I don't think so. Maybe as a base for a turbo drag car.

There may not be a physical SEMA Show this year, but that hasn't stopped a number of brands from debuting their latest and greatest products. Here are five to check out.
Although Titan makes direct replacement, large-capacity fuel tanks for a number of truck models, fuel tanks for recent GM Long Bed trucks were not available—until now. Starting at $1399, Titan is offering 66-gallon tanks replacement tanks for Long Bed and Crew Cab Chevrolet and GMC trucks built from 2017-2019, as well as a 60-gallon tank for 2020-and-up Crew Cab and Long Bed trucks starting at $1349.
Titan notes that all of its tanks are a direct replacement for the stock part, with shipping for the 66-gallon tank starting on December 1, and the 60-gallon tank starting January 4. Visit titanfueltanks.com for more information.
Based on the 5.3-liter LM7 found in GM trucks and SUVs built from 1997-2007, Summit Racing points out that its remanufactured 5.3-liter LS is “ideal for track day builds.”
Rated for 450 horsepower and 420 lb.-ft. of torque, the engine comes configured with a 10:1 compression ratio, hypereutectic flat top pistons and Summit Racing Pro LS roller camshafts. As well, each engine is built by ATK and backed by a two-year, unlimited mileage warranty. Visit summitracing.com for more information
Built out of chrome vanadium and featuring an open-end design, these Hyper Race lug nuts fit sizes M12 x P1.5 and M12 x 1.25. The lug nuts can be had in either black or titanium chrome, with a choice of red, blue or yellow ring.
Each pack includes 20 lug nuts and a special key adapter. Visit mackin-ind.com for more information.
Nankang’s newsest tire sports a 200tw rating is billed as being “specifically designed for Club Racers participating in Autocross, Time Attack, HPDE & Circuit Racing.” The CR-1 also features an asymmetric tread design to increase rigidity, as well as a sidewall reinforced with aramid fiber. Visit nankangusa.com for more information.
Featuring a fully programmable warning feature and built-in peak recall, the Supreme Series of LED gauges require no extra controllers or anything else to get them running once mounted.
Speaking of mounting, the gauge’s thin design mean only a 1.25-inch mounting depth is required, and all gauges are set up to be daisy chained, meaning that only one gauge needs to be grounded and receive power for the whole set to function properly. Visit prosportgauges.com for more information.

Because regardless of any other factors, engine block material is the difference between winning and losing at a track day...LOL

my iron block 5.3 240z is such a pig at 2430# 
Thanks to those lug nuts I learned what Chromium-vanadium steel its today (From Wikipida)
Chromium-vanadium steel (symbol Cr-V or CrV; 6000-series SAE steel grades) is a group of steel alloys incorporating carbon (0.50%), manganese (0.70-0.90%), silicon (0.30%), chromium (0.80-1.10%), and vanadium (0.18%). Some forms can be used as high-speed steel.[1] Chromium and vanadium both make the steel more hardenable. Chromium also helps resist abrasion, oxidation, and corrosion.[2] Chromium and carbon can both improve elasticity.[3]

You need an aluminum block so you can have a lightweight race car like my 3000 lb. LS-swapped Z-car.
Wait...
What's the weight difference between aluminum and iron LSs?
I figure there are enough aluminum ones that it makes sense to lose weight that way if you care unless the price difference is really big, or the actual weight difference is small.

Having 80 pounds of nose weight that doesn't need to be there is losing no matter where you are.

Well.... Weren't stock Zs in the 2200lb range? And the L24 was a stonkin' heavy engine.
Not saying 2430 is bad, but also, you didn't spend probably $4k for a reman engine from Summit either.
