small block to big block

The swap is not as bad as it sounds. Go to Schumacher creative services and get the swap kit with the instrutions for your car. A little trimming and drilling on the K-frame and it will drop in. You can keep the small block torsion bars if you want. The front end will bush more on the turns if you take them fast. For the strip they will work fine. Yes you will need another driveshaft only if you change the rear axle or your 360 has a 904 trans. You can keep the rear axle you have for now if its a 7 1/4, but I would make plans to change to a 8 1/4 or 8 3/4. With the Schumacher headers my 440 make 500 Hp on the dyno and you do not have to cut the fender wells.
