I did say that IMO most guys with an SS would be "happy" with PS4s, never said nor alluded to an SS would out handle a ZL1 with said tires.

Cheap FBO: E85, tune, CA front cat deletes, cut air box + green filter, Pray ported intake and TB say $1700

I got money to burn: E85, tune, LTs + green cats, RotoFab, ported MSD, 103MM TB, 3" exhaust say $4500 to $6000.

I'd say off the cuff WHP difference 20. Clearly the cheap FBO, - increase in resale would only cost $700 over 5 years... chump change for the fun added.
Nobody tends to talk about this but I also factor in the general cost of a catastrophic powertrain failure (engine, trans, clutch..) when considering modding/no warranty. The LT4 seems to be more reliable and has a higher power ceiling than the LT1, as it comes pretty much all forged. The cost of the LT4 is almost double the LT1 (comparing noew complete motors). All factors.

I bought my ZL1 slightly used with 900 miles certified for $56k and find the all around performance under warranty satisfying.

In the end modding and racing is a slippery slope endless money pit for power junkies...

Not overthinking it like me, if you just care about straight line performance, the gen6 SS or especially the 18+ Stang 5.0 (I know this is a camaro forum ) are probably better bangs for the buck, especially if bought used and building from there.
