Tim & Andy put together one heck of a little car, I've always admired it from afar and am super thrilled and honored to have the opportunity to be the next owner. Once I get it in the shop I'll be evaluating everything and getting to know the car. After that I'll form a game plan for any developmental changes.

I'm a happy guy!

Congrats on the purchase Scott...

A 3.91 rear gear with the Passon 5 speed would be a pretty good compromise. That combo would have a 10.5 overall first gear ratio which is maybe a tad steep but it should work. With the 0.70 OD ratio the top speed at 6000 rpm would be 165 mph. Not sure the engine can push the car that fast but it might. Tim has had the car to 155 mph and he said it had more in it so maybe it will go 165.

The carb is only a 650 so if a person really wants big numbers rather than drivability then there is another 20-30 hp available from putting a bigger carb on it.

Only problem I see is that the driveshaft wasn't designed for that rpm. With the 0.7 OD the shaft speed will be 8600 rpm at 6000 engine speed. I don't think the aluminum shaft can handle it so the car will probably need a carbon fiber shaft.

Why not a T56 Magnum?
Then one can drive the car to and from the track using a 6th gear!

That was a good deal.
I would leave the rear gear and put a GForce 5 speed with a steeper 1st gear.
That would keep drive shaft speed down.

I have a Doug Nash 5 speed in my car with the deep first gear and 1:1 fifth gear but those transmissions don't really fit in a Mopar. Besides not fitting, they are clunky and loud and generally a pain in the rear.

The Passon is a good compromise for a car like this. It is probably 20 lbs heavier than the trans that is in the car but the weight is close to the CG so it shouldn't upset anything. The driveshaft speed is just one thing to deal with. Carbon fiber shafts are expensive but certainly not a deal killer. Just part of the price of having a 150+ mph street car.

With the 3.91 gears the car will probably run mid-elevens at the drags. It isn't set up for drag racing but with those gears it would get out and go.

Even though I don't even have the car yet I can tell you this much, if it gets a trans swap it'll be the Passon, because it will fit, it's strong, and I already have it. 3.91's are an easy choice since I have a brand new complete Yukon based Dr. Diff unit already as well. If it needs something else down the road in either case I'll look at my other options when the time comes. Andy, what does a CF drive shaft run these days?

Yes, that one. It's in to have the 340 side stripes and rear panel stripes added right now.

Is that the one I delivered for you? or was it the three speed car?

Mark Williams 3.75" is $1034. http://markwilliams.com/driveshafts.aspx

No Jim, the one I'm selling is it's near twin (but a 4 speed #'s matching car). The 3 speed car is still on the rotisserie, that one will be back on it's wheels again this week sometime short of any delays.

Looks like I'll be digging out the wallet again

Glad to see Tim's car went to a good home!

Scott- where will you be tracking the car?

I think most of the talk about Tim's Valiant was between Wade and myself

Most of the time right here in Spokane, but as time allows I'll likely drag it around to other West coast tracks.


*Wade.....I look forward to chatting with you at length down the road

Yea it's kind of ironic "Mr. Numbers Matching Guy" is selling his only 100% #s car and buying a race car. Those who know me well know that as much as I love O.E. cars, I've been a racer forever too


See ya on the track!
