I vote Passon because of three reasons: 1 Customer service before,during,and after the sale. 2 You only have to change a few things for the swap,driveshaft,shifter,bellhousing,speedo cable,etc are all re-used for the Passon conversion. 3 If you ever need a repair part or any type of service work done the Moparts Community is ready to help and your factory service manual is still good.

Both have their ups/downs IMO.
Pros to the Passon unit is he's got a great reputation for being one of the good guys in the hobby and he stands behind his products. Plus like mentioned already, it's a stock replacement trans, so you can reuse everything else. Cons to his piece are the o/d gear is only a .80. Now I think he did that to keep the gear spreads reasonable for performance driving, but it does hurt his o/d's usefulness on the highway. However, if you've only got a 3.54 rear, you probably don't need as much of an overdrive ratio as say someone with a 4.10.
Pros to the keisler is their available .64 o/d. That really knocks down the RPMs on the highway, and the extra gear of a 5sp makes it so you don't have to worry about far gear spreads, because the race will be over by the time you are at the end of 4th anyway. Also their trans will have a more modern shift feel to it. Cons is you have to change a lot of components to make their trans work. That trans doesn't shift well if you rev your engine much over 6k rpm from what I've heard. If you do a search you'll see some members who've had problems with this trans, though I think most of them have been since resolved by keisler.

Having driven several Kielser equipped cars and a couple Passon trans cars, here's my .02. 1. For a true "no hack" install the nod CLEARLY goes to Passon 2. If you drag race you'll like the Passon, the Kielser is not a fast shifting trans, a bit too sluggish and notchy, especially at higher RPMs 3. If you want the strongest trans, Passons will take more HP than a Kielser by a fair margin 4. For cost and ease of install, Passon wins 5. For the best highway crusing O/D situation, Keisler wins due to it's better high gear ratio 6. Fuel milage Kielser also wins, same reason 7. Service - Passon hands down 8. With a 3:54 geared car that you do not want to modify beyond clean/simple easily reversable bolt ons and is mainly street driven and occasionally drag raced - Passon 9. For a modified car that is mainly used for local car shows, street cruising, taken on a good many long highway runs and not much else - Kielser 10. If considering these two companies you should also look into Gear Vendors and Classic 5 Speed before buying, may as well see what everyone is selling before you pull the trigger. I have also driven Gear vendor equipped cars, they should be a consideration for sure, they make a good product.

I fall under this group and I have a Kielser. I think you find the cost is about the same between the two unless you can just change gear sets.
Also it depends on what type of car you have. B-bodies seem to have the least amount of troubles going to the TKO. I have an e-body and there is no way you can get the trans high enough without modifying the trans tunnel. Which to me...... is no biggie.

I recently installed the Keisler TKO-600 in my 69 Coronet R/T convertible, which was an automatic.
The kit showed up 100% complete 8 business days from when I called and ordered it, the parts were 100% correct for my application, and both Richard and Gene were really nice to deal with.
I used the hydraulic clutch setup, which requires drilling 3 3/8" holes around the factory hole in the firewall where the stock clutch linkage would go through. I then of course had to cut the hole in the floor for the top of the trans and shifter to come through. I will see if I can get a couple of pics for you.
In the end I don't think the hole was all that drastic, the parts and support were great, and I absolutely love the results. I've got it coming up through my factory AUTO console with just replacement of the top plate to the 4-speed style. The shifting was a little stiff for the first 250 miles, but now is really starting to loosen up and it shifts great.
The complete conversion kit was not cheap, but count me as a very satisfied customer, if you were close to Miami I'd tell you to come and drive my car.

How much pain do you like?? If you like a lot of pain get the snake charmers product. If you want your life to be simple and full of smiles as you drive your car down the road get the Passon product. As far as the mumbo jumbo about the passon gear spread...just more ... The gear spread on the passon overdrive is Goldilocks...just right!! And don't forget I haven't a clue what I am doing

I don't know if you have a clue or not, looks like you have a nice looking Plymouth and you made it to track day. Are you famous?
I'd consider myself just knowledgeable enough about my old car to be slightly dangerous when I start any project. I installed my TKO-600 from Keisler over about 3-4 days and it seems to me that it went in and works "as-advertised"... and I'll admit that I haven't a clue what I am doing, with old cars or just about anything for that matter.

Put a Passon in & forget about it. I did & I'm 110% happy with it in my 69 Bee with 4:10's. Went from 3200rpm to 2300 SWEET!!! 511 inch & 8 3/4 here. Car looks bone stock with 26" Goodyear PolyGlas tires
Your math seems a bit off. Should be closer to 2600 rpms???
