it must get old seeing the same thing whenever someone opens the fridge/hood

You mean, like everyone's goal: a Gen-II hemi? You know, "for the wow factor"?

Strangely, this same argument was current when people started replacing their 150 hp (3/4 race) Ford flatheads with 200 hp (stock) 1949 Olds, 1949 Cadillac and 1951 Chrysler junkyard engines.

Sorry, the combination of easy availability, low costs, and super power is very compelling.
For those not familiar, the LS series features:
1. Aluminum heads (yes, every single one). Despite the comments that appeared here in the Trick Flow post, multi-angle valves (BBC, Boss, 385) are not needed for excellent ports. All LS heads are wedge with parallel valves. 2007-* 6.0 & 6.2 square intake ports (including trucks) flow over 300 cfm as-cast, as-installed.
2. Aluminum blocks in all cars and many trucks. New factory replacement aluminum block: $1,200.
3. 6 bolt cross-bolted main bearings caps (yes, every single one).
4. Factory cast crankshaft safe to over 1,000 hp on boost (less N/A or nitrous).
5. Factory 1.7 rockers are safe above 6,500 RPM.
6. Stock pushrods are only 7.4" long.

LS engines are almost 20 years old, get used to it.
