Tranny first gear combined with rear gear help

hey guys,

thanks for the advice...havent calculated what gear or rpm i will be going through the traps yet....does make sense to want to be in fourth though since shifting to 5th overdrive gives a prety big drop in rpm's...In regards to the TKO, i hear about too many problems with those trannys to want one right now...id rather build a g force t5 if mine breaks on me (mind you the g force stuff costs almost as much as a tko)...im just going to have to see what happens with the t5 reliability wise....im going to just stick with the 3.91's for now and see how that goes...i still have 3.23's to use if i want to go with a lower numerical ratio
