the air bags wouldn't be the weak link of your rear, it would be the control arms. There's some guys that run bags on there drag truck so they can get it down in the weeds when your at the track. If your gonna run a 327 and only rev it to 6500rpm you should be fine with the stock control arms or stock leafs. You can re-place the coils with the bags and adjust the rear for the right pinion angle and run it that way. Or if you want to save some more weight I've seen guys make there own control arms out of mild steel square tube. Or if you wanna get real crazy stick a 4 link under it with the bags and that would be perfect for racing. If you want your truck to hook at the track I would not use them in the front
