i want to put a gtp drive train in my car and dose anyone know what cv shaft i will have to run
If you run the 4T65E-HD, you'll need custom axles made. I spent $500 on mine from Dutchman Motorsport.
If you run a J-body trans... ie 5 speed... then you use J-body axles.
You can use the factory 4T40E axles or you can get the CV joints from GM Racing to run porsche 930 axles, also you will need a drive sprocket set from GM racing wich will cost you $725, and if you are using a Torque converter clutch you will need an input shaft from intense racing $450, and the engine and transmission will need to be tilted 22 degrees, which will require a modified pickup and pan. Also you will need to get a stand alone controller, I recomened Powertain Control Systems for that. Im in the midle of a swap and getting all the parts and GM racing told me exactly what im going to need,
