so, factory..is the crossmember differnt from the camaro to the firebird? inquiring minds want to know. keep in mind i'm about 1 month before startup, before teardown and paint. i'm in the 50G neighborhod on this car. If its actually a better idea to relocate the motor mount holes, I'm at the point I can do that. Engine should be around 515hp plus two 125 shots of nitrous at the strip, mini tubbed. ect. ect. ect.
