8 1/4 sure grip questions

i had a 318, 904, with 3.55 gear very streetable and a good combo. the only difference is i had the low gear planetary set put in my trans. makes the car at take off more like a 3.91 but still the higher gear of a 3.55. just an opinion but works good. for highway and ocassional burnout the8.25 with posi will be just fine. have a good one :salute:
