Keep in mind that full set of higher-end bolton NA work (intakes, headers, CBE, UpRev, tune) runs you in the ballpark of 3-4K+, maybe a lot + if you're paying someone else for all the labor, and gets you from stock's ~270 to ~310 (so somewhere in the neighborhood of 10-15% over stock).
I'm pretty sure the 414 number on the SC is in RWHP. You could call them to double-check. Real-world numbers versus stock (not versus a fully bolt-on'd motor), it's nearly a 50% gain in engine power. 8K+ for that is a steal compared to the 4K+ for the boltons.
