Sale-proof cars that people butchered......Why?

Ive said before that I hate people butchering classic iron. Now I'm not the type that thinks an SS396 Chevelle is "ruined" because it has an HEI distributor, halogen headlights and radial tires. On the other hand-I hate seeing '58 Corvettes with LS3 engines, six-speed automatics, rack&pinion steering, etc. Ive said many times sports car guys are smarter-you never see a '71 Datsun 240Z with the engine and tranny out of a 2011 370Z or a 1969 Porsche 911S with the drivetrain out of a 2015 Carerra, or a vintage Jag XKE with the motor and tranny out of 2017 F-Type. Ditto for motorcycle enthusiasts-you never see a 1971 Harley Super Glide with the engine and tranny out of a 2009 Softail, or a 1973 Kawasaki Z1 with the engine and tranny out of a 2014 Ninja !! Lately I've seen a bunch of cars in magazines and on the internet that are completely sale-proof. Their owners better love them-because no one else wants them at any price.  #1 This guy put a 389 Pontiac in a '57 T-Bird. Why would you do that? This car outraged GM and Ford guys alike. If he wanted more power than the ancient 292 / 312 "Y-Block" why didn't he swap in a later 302 or 351W? Or even a 390? At least a Ford engine, right? Ugh. # 2. This guy had a Chevy LS engine in a Fox Mustang. Again-Why?  Not performance. I know guys that are running 10s with 302s and 347s. An LS swap into a Mustang is an absolute nightmare, and what do you gain? Ford guys don't want it, Chevy guys don't want it. # 3. Angered the muscle car crowd and the import tuner crowd because he ruined 2 classics. This clown put the engine and tranny out of a 1998 Toyota Supra in a '67 Camaro. And he couldn't understand why people were storming his house with torches. # 4. The all-time more money than brains winner goes to.....The guy who put a 426 Hemi Crate engine in a Ford / DeTomaso Pantera!! Sports car guys lost their minds, Mopar guys lost their minds, and Ford guys lost their minds. A Pantera is a cool car. They look like a Ferarri, and they had a 351 Ford Cleveland V8 mounted mid-engine. And they were really fast. The buff magazines called them the "Poor Man's Lamborghini"-although at $10,000 in 1972 dollars-no poor people bought them. That was more than a Porsche 911S.  A Pontiac Trans-Am was $4,255 in '72. A Corvette was $6,000. Anyhow-again-if he wanted more power there's tons of speed equipment for 351C's-Edelbrock and Trick Flow make heads,Crane, Comp Cams and others make cams, etc. Or a 429 / 460 has the same bellhousing bolt pattern as a 351C and isn't much larger externally. But a Chrysler Freakin' Hemi?? Arrrggghhhh!!!!  # 5. This guy spent $250,000 that's not a typo-I didn't mean 25K, I mean a quarte of a million-putting the Turbo Diesel engine and Allison Transmission out of a 2014 GMC 3500 truck into a 1970 Chevelle. Why? For 100K you can buy numbers-matching LS6 Chevelles and 427 Stingrays all day in any of the 50 states, as well as Boss 302 Mustangs, Ram Air IV Judges,  440 Six-Pack Road Runners, 'Cuda AARs.  For 250K you can buy numbers-matching Boss 429s, or 427 Shelby Cobras. But this guy wants a Chevelle with a Diesel in it.  # 6. This clown spent 100K building a Kit Car-a Porsche 356 Speedster Replica. Now most of these kits cost about $20K for the complete kit which usually includes everything but the engine and tranny. Most guys go with a pumped up VW 4-banger, which will have more oomph than the original Porsche 4-banger, look and sound correct, and be dead-reliable. For $25K you could have a nice replica of a car that sells for 100K+ if it's original. If you wanted to invest a little extra bank-you could put a 6-cylinder 911 motor and matching tranny in it, and it would really rock. And still cost maybe 40-45K. No this genius spent 100K putting the drivetrain out of a Subaru WRX in it!!!  Porschephiles went ballistic. Kit Car guys rolled their eyes. Who in the hell wants a Porsche replica with a Subaru engine in it???  If he had 100K to spend why wouldn't he buy an original?? For 100k he could buy a prisitne '70'sor '80's 911 Turbo Carerra!!! He was shocked that when he tried to sell it he got zero offers. No shit sherlock!!  I don't know what these people were thinking. Mastermind
