Preparing for a possible 727 to 5 speed swap. I am looking at SST and I was quoted the TKO 600 which has ratios of 2.87, 1.89, 1.28, 1.0, 0.64.
Their other option is the TKO 500 with ratios of 3.27, 1.98, 1.34, 1.00, 0.68.
I am not ashamed to admit that I know next to nothing when it comes to this so any advice would be appreciated. Would the 600 be better for my needs?
71 Demon, 340, 3:91, 28 in rear tire. Most all of my driving will be highway with possibly a track day once or twice a year. I recently swapped an open 3:23 rear for the 3:91 with sure grip. I love the difference on the low end but cruising is pretty brutal at 3k rpm at close to 60 mph.
Thanks.
