5.7 L Hemi, ZF 8HP70 Swap

I think the problem is you're being a little too rational here... We're talking about classic muscle cars here not modern tuners or race cars. For a person to be willing to sink his/her time and money into swapping a new engine into an old car they have to be a little "irrational" in the first place IMO. This hobby is a lot more about emotion and feeling and the excitement of driving an old car than spending the least amount of money to go fast. Like has been said if you want to save money by using an LS motor there are millions of old GM vehicles out there to put them in and a HUGE aftermarket to build the rest of the car to drive like a modern 'Vette. I just don't understand why you would bother to get a Mopar and then put a GM engine in it when you know at least 90% of either GM or Mopar fans would hate the idea. Yes it's 'your car' and you can do whatever you want with it but whether you like it or not unless you keep the car locked up in a garage and never show it to anybody, guess what you are gonna run into people who take one look at that LS in the engine bay of your Dart/Cuda/whatever and say "huh that car's been ruined..."

Muscle cars aren't about being rational in fact muscle car fans are probably the least rational car nuts out there! Myself included for sure...

These are "tuner cars and race cars" by definition of whats being done to them. what would you say give/take 5-10% of this forum build these cars as 100% oem for shows while the rest build street/strip cars, tuned cruisers, the rare roadrace setup, or pure strip cars

Why do an LS in an RX7? Why do an LS into anything old? Afterall, there are plenty of second hand camaros, corvettes, etc that already have them and we've all seen those build to absurd scales. Why would anyone do such a thing?? Could it be that someone likes a particular look, but doesn't want all the downsides of what the factory offered?

As for the dimwits who would tell me "I ruined the car". That's his simple minded opinion and means nothing. In 40 years presumably the LS car will still be driving around because it has something to offer to the next generation of car nuts. The purist car? Locked away in a family garage with no one to drive it or rotting away in a yard.

I'm sure the owner of this car would laugh in the face of a purist if they said he "ruined" this car:
