^^^all valid points....for example my buddy had my old 2200 on it but didnt have the budget to do the converter his 60's suffered and best he could do was a 10.32 with the 3.6" pulley....i told him add boost with the 3.48 and a converter and hes got a 9 sec pass....well first day out with his new combo he ran 9.91 at 139 so your definately correct....he was running a 331 gear...

my car has since gone under the knife, sold the stock shortblock and went to a sleeved shortblock....sold the JT and now have a YSI-B and she made 1040/765......2.95" upper with 20% Lower...im hoping she will pull an 8.99 if im lucky enough...

my car is a 15 auto centri with 3C converter 3.15 and STOCK halfshafts....1.33 60ft. i think the 3.15 works great...i just ended up doing the dss 1400hp shafts and retiring my stock shafts intact and good as the day i got the car....i think my car would 60' worse if i had steeper gears....further more i would never trade 1/8 for back half mph....id rather have a killer 60' then a mehhh 60' and make it up on the big end with mph....especially in an auto car the thrill is all off the line anyway...once your in 3rd its essentially a wot highway pull, if i could i would even go to a 3.08 as the only draw back i see with the 315's (atleast in my car) is that it shifts 4th just before the end...
