!!! new best but broke the rearend!!!!

my best last year was in the 6.92's/ 98-99mph. not a real wild motor, around 13.5 on sunoco 114. decent home port job on some 915's- mallory points and a 6t box. pretty simple car. 383 don't twist my car up so that's why I think the cage was a waste. I got a buddy running a 360/408 that's running almost the same numbers as me. I'm kinda dissapointed in my motor after seeing what that 360 will do. My car is gutted/tubbed/ and caged. Is yours still all car or just a track car?
