Which to get: TKO 500 or TKO 600?
I plan on doing a 5 speed swap and I need your help deciding on what tranny to get.
~I am making 405 HP/385 TQ at the flywheel. I have 3.73's in the rear.
~The TKO 500 has a 1st gear ratio of 3.27, and a 5th gear ratio of .68
~The TKO 600 has a 1st gear ratio of 2.87, and a 5th gear ratio of .64
Here's my dilemna: Will there be too much gear multiplication between my 3.73 and the 3.27 1st gear ratio of the TKO 500? Would I be better off spending the little extra money for the TKO 600 for the 2.87 1st gear, the little bit better overdrive ratio, and the added strength?
I'm afraid with the power I'm making, that the 3.27 ratio of the TKO 500 would be totally useless, so that my tires would just spin. Or do you think this isn't worth worrying about? Then again, if my tires didn't spin, the car would accel a little better in 1st.
So what do you think Corral--the TKO 500 or the TKO 600, and what's your reasoning? Thanks,
