any suggstions, i have a mild 308 (low to mid 300hp) with a 3.36 diff, and in between a t400 which has been kitted with a hi stall converter . I'm going to be running 255 60 x 15 on the rear. but Im defiantly going to get a lsd diff made up once it's all up and running and i have saved enough for one.. any suggestions on ratios? i figure because of the larger tyre/rim combo i should maybe go up 4.44.

the van will only be used on weekends and i want it to get off the line reasonably well. with the occasional country cruise.
