8 3/4 vs 8 1/4 weight
Well a little bit of extra weight for drag racing right over the back tires it's probably going to help more than it's going to hurt.. filled 100 lb for 10th of a second so if you have an extra 50 lb that could be a loss of a half a tenth of a second LOL and if you're running a stock engine you're not fighting a half a tenth of a second but then again that half a tenth of a second could be made up with attraction you get with a little extra weight over the back tires... As far as strength my eight and a quarter lasted until I sold it and my well built eight and three quarters lasted about 20 passes till I put in a Dana 60... This was all heavy drag racing and the weight didn't come into any of my calculations...
