HamadUp didn't buy from Keisler and he's enjoying his:

The TKO is using a 26 sp. and 1 1/8 in. size input shaft, so if the old trans. has the same input shaft then you can still use your old clutch disk.
I also recommend to go with the hydraulic clutch from AP, excellent feel and less effort.

Buy a Richmond 5 speed, use all of your existing parts and have a better transmission in the end. The richmond bolts right in, the only thing you have to change is the transmission mount.

I bought mine from American Powertrain and waited for a week or so to get it shipped. The guys there were so knowledgable and helpful, I really liked their 24/7 tech. help line, esp. for me being overseas.

MyRed69,
Great advice.
I had great customer service with Keisler, for what it's worth. They sent me some of the parts ahead of time so I could get things ready (hydraulic clutch m/c, speedo cable) and were able to send me some quick parts that were missing from the first few kits out the door.

The Richmond vs Tremac discussion is missing an important point. If you have a 3.08:1 differential and don't want to change it, you've got to get a Richmond. The Richmond 5 speed has a 1:1 ratio on fifth gear. Richmond's first gear is much lower, numerically higher, than the Muncie. With a 3.08:1 rear end, the Richmond will give you a lot of power in first gear.
If you've got a 3.73:1 differential, and don't want to change it, you've got to buy the Tremac. Keeping discussion simple... their first gear is the same as the Muncie, but their fifth gear is an overdrive.
Also, I've never driven a Tremac. My experience was that with a new Richmond, it was difficult to shift at first. It smoothed out with use.
Anyone else who's driven both trannies?

I have a 3.08 rear and a 0.64 OD, its useless when cruising less than 60 MPH, but I really enjoy it when cruising the highway at 70-75 MPH. You can still get the 0.82 OD which makes a great 5th gear with the 3.08 rear end.

Richmond also has a 5 speed overdrive transmission. Not sure I have seen anyone put one in a C2 or C3 though. Has a higher tourque rating than the non-overdrive 5 speed too. It is called the super street I think.
I just talked to the American Powertrain guys at Kissimmee. Nice guys and nice product. I have never read anything negative about them either.

I also considered the RS600 and a 3.73 rear, but the wait for the RS isn't worth it for me.
My last option is to keep the 2.87 and go with a TKO500/RS500. I would get a great first gear, but don't know how the other 4 gears would do with such a high rear end ratio.
Did you call around and find out who has the best price?

With the 1 to 1 final drive with the Richmond you're not really getting the advantage of having a 5 speed. A trans with a .67 overdrive would give you, perhaps 1800 rpm at 60 mph. The Keisler RS 400 and RS500 have a 3.37 first as well which would give you great acceleration out of first gear.

His best choices are TKO600 or RS600, with TKO600 being the first choice.

I recommended the TKO600 due to first gear/rear end ratios. You want to multiply the first gear ratio by your rear end ratio and be as close to 10.0:1 as possible.
TKO600 2.87 x 3.55 = 10.1
RS600 280 x 3.55 = 9.94
TKO500 3.27 x 3.55 = 11.6
RS500 3.37 x 3.55 = 11.9
IMO the lower first gear of the TKO500 and RS500 would be overkill. I would recommend the TKO600 because you don't have to wait over a year for it. Also, the TKO is a whole new unit and the RS are rebuilt Transmissions.

Well, I'm going to have the 3.37 first gear with 3.70 rear end so I'll see, LOL. I calculate that'll put me at 38 mph at 6000 rpm in first, a slightly lower speed than the 40 mph at 6000rpm I feel will provide max acceleration for a motor producing 325 hp at 5500 rpm.

Because it has shift gates it is also supposedly much less likely to result in a missed 2 to 3 shift.
Wait times on the RS400 and RS500 are 4 to 6 months. Wait times on the RS600 are about 9+ months but it also has the 2.80 first rather than the 3.37 of the RS400 and RS500.
