I get comments about my numbers matching RS/SS being hacked up because I want to build the car for me to drive and drive hard I will. The transmission was sold to another camaro owner and replaced by a Viper T56 six speed, the engine is sitting on a pallet and has been replaced by an 89 TPI that has all forged internals and sports a 78/75 turbo with megasquirt MS3 engine mangement. The factory 12 bolt 3.07 diff was swapped out of the stock housing and an eaton posi with 3.73's are inside. So build the car the way you want and don't worry about the comments. If you want an all original time capsule or an all out race car, do it your way and enjoy the car.Will headers ruin the stock appearance or is that an "acceptable" upgrade? Looking for opinions
