I still don't get the negativity.
CS was hired by Chrysler Corp. to develop performance models from their existing lineup. Considering what he had to work with, I don't think he did too bad. The 2.2L four cylinder was a well engineered motor. Turbocharging, common today, was leading edge then. Ultimately a 4V cylinder head was developed. Drivetrain details included equal length half shafts to combat torque steer.
Chrysler offered Direct Connection performance parts for them and even a performance shop manual. There was aftermarket support too. Shelby Dodges competed in road rallys, showroom stock, drag racing, and ran at Bonneville.
There was even a Chrysler-Shelby Performance Center in California where they did development work. During this time CSPC engineers were evaluating a Shelby Daytona with a turbocharged, inter-cooled four-cylinder with a 4V head. As for "how much power can you put through front wheel drive. .." this test mule had an all wheel drive configuration.
Don't take my word, try to hunt up a copy of Dodge High Performance, published by Petersen Publishing. It had seriously competent performance technical information.
There was even the Shelby Dodge Automobile club for enthusiasts. I think it was located in West Redding, CT.
All that has long since evaporated from the automotive performance landscape. But I think that Shelby and all the employees and enthusiasts who invested time, effort and money into improving and competing with these cars deserve a modicum of respect.
