OK folks, I'm converting my car from 6 cyl to V8. It'll be a 289/C4 with an 8-inch, so essentially just a stock V8 car as far as this topic is concerned. I need to knowif my original driveshaft will work? Like if it's the same. I know on the C4 end it is the same, because the car had a C4 in it originally, but I'm wondering if things will be different because of the rear-ends. Any thoughts? Help, HELP!!
