Well my Top Loader was showing it's age and in need of some serious work, plus I didn't like the extreme high first gear ratio that comes with a close ratio. BUT, I don't like the extreme LOW first gear ratio and extreme .6 over drive that to often comes with a T-5 either! What to do?
TKO-600, road race specs, was my answer. The TKO-RR has a .82 overdrive so it's not SO high. And a decent first gear ratio that isn't TO low.
Depending on your cam profile, expected crusie mph/rpm range, rear gear ratio, size of tires you might want to consider a .6 over drive. I suspect for most folks the .8 really is the best overall ratio.
Piece of cake changing out the Top Loader for the TKO. I used the existing top loader trans mount, tranferred to the TKO, and it LOOKS like the exisiting speedo gear will work as well. I've got the back tires jacked up off the ground and have been going through the gears to break in the trans, check out the speedo, clutch action, etc. Looks good.
New clutch and pressure plate, to fit the new trans, but you want a new clutch and pressure plate regardless of what you had with a new trans anyway. Also new throw out bearing and clutch release arm. In my case I drilled out the end of the clutch release arm to accept my existing slave cylinder to throw out arm linkage. Everything lines up good, no need to change any locations or angles here.
