Shelby Dak Challenge Car

Could be interesting to see 3 Dakotas at the challenge.

True. What you do is *trade* parts to yourself, for parts of similar FMV *that you already own*.

Problem is that I would set aside the "new" Shelby's factory wheels and replace them with Diamonds. I don't want to sell the original wheels to someone else.

either charge your challenge budget for the diamonds, or buy the diamonds now so they're "something you already had laying around" when you trade them to yourself the day before the challenge.

self-trades have to have equal FMVs. you can't add money to your budget by trading an "expensive" part off your challenge car for a cheaper part from your stash. if the shelby rims are grossly more valuable than the diamonds, then you'll have to bring some other stuff from your stash along with the diamonds to equate the FMVs.

per and i discussed these self-trades on the old board before the '04 challenge, and this is how it's been ever since.

Basically I have to fabricate a Top Shot kit that could shoot down my TBI?

I can run the Shelby wheels as well. I can go 225 wide. I am sure I can find used 225 15 inch tires.

Yep, they were throttle body injected til then. Oh boy, I might just have to finally make it to a Challenge if there are daks competing.

I forgot about the Top Shot. That's the concept I was thinking of, but was recalling the rental Neon Mopar Action abused at the 'Nats years ago.

If I'm right, an aftermarket 4bbl air cleaner housing will fit right on the throttle body. I can test fit an aftermarket base on mine tomorrow if it helps.

And Lesley, yes it will be cool if three Daks show up. Now go get your hands on another one (I know your good one is well over Challenge money) and make it four!

I have an aftermarket Edelbrock air cleaner for a 4bbl and it fits, I like how the top shot nozzle attaches to the threaded rod. Of course it has four sprayers. I am not sure if they would spray down the TBI.

I was considering the Dak to be different. That is not going to be the case. I may buy the truck to save it from rusting away or getting beaten on by some kid, but since getting it into the 13s or making it run the autocross competitively are likely out of the question I am losing interest.

Well it is different. It just happens to be the same different as a couple others here.

I still have a tailgate I can spare. If you decide to take a pass on the truck or want to sell it off after pulling the pieces you want for your good one keep me in mind.

How much for the tailgate?

I'll take some pictures a little later today and send them to you. How's $25?

If I buy the truck $25 is more than fair.

Interesting trivia: The TBI unit on these trucks was built by Holley, and they later re-used the same TBI casting design for their two barrel Pro-Jection kits. The biggest difference between the OEM and aftermarket TBIs is that the Pro-Jection wasn't drilled for idle air control.

Are you sure about that? I wonder how difficult it would be to modify?

Holy crap! I just saw a pic of a Pro-Jection 2 TBI unit and it is VERY similar to my stock Shelby unit. Now here is an important question. My Shelby #233 has the factory TBI adapted to an Edelbrock Performer Manifold. Could a projection 4 TBI be made to work with the Shelby's electronics? The 4bbl TBI would bolt to my manifold. Does anyone have a close-up picture of either Holley unit?

The Shelby ECU has no known tuning options to let it know it suddenly has twice as much fuel flow rate, and no outputs for the second injector pairs.

I'll see if I can get a picture of the Pro-Jection TBI we have lying around the shop sometime soon.

Jet will make me an ECU for the Shelby (may not fit itno budget though) for any mod I want to perform. I have been through this with jet with my #233. I looked at a close-up pic of a 4bbl unit just now and the connectors look identical to what I remember by Shelby TBI having (have to run out to the garage and get one of my extra TBIs (I have several extra if anyone cares.)

I don't think I would be interested in intalling a Projection 2 on the Shelby as the TBI unit appears to be nearly identical (no real advantage, although it coiuld flow a bit better), but the 4bbl set-up would be interesting. For the Challenge Truck, I could just go carb for the event and re-install the TBI later to keep it original. Also, a magnum 318 swap could work with the Shelby.

You might want to check their definition of "any" - they're likely to draw the line on adding injector drivers if the board isn't already equipped with non-populated injector driver circuits and there isn't some support in the original processor firmware for more than two injectors.

Very true. I would be happy with a bigger, better flowing 2bbl TBI. I am starting to think Magnum.

Back when the Shelby Daks were new, both Shelby and Mopar Performance were offering an upgrade kit for the trucks. It was a 2bbl TBI from a 360, template to open up the 318 manifold for the 360 TBI, and a re-calibrated ECU. The kits are pretty much hens teeth today.

For my friend with #1459, I was thinking a modern version of the kit would be the 360 TBI on either a modified stock intake like the original kit, or with that adapter on an Ed Performer, and use one of Matt's Megasquirts in a gutted stock Mopar ECU housing.

Depending on what Jet charges it might be cheaper to go with the Megasquirt. It would be more flexible too.

OK, I need to get back to work on mine, and get those tailgate pictures.

Jet will charge Me about $300 and it is plug and play. I have pulled 360 TBI's in junkyards and it is the exact same as what I have. I then went and checked 318 TBIs and they are also exactly the same as what I have. I have my TBI on an Edelbrock Performer thanks to a Jon Steiger adapter.

My biggest problem with the Dak is that buying it for $1200 (won't go lower than that) does not leave me enough money for shocks, tires, paint and a way to get it to run the quarter mile in under 15 seconds.

There used to be a guy that sold custom-fabbed 4bbl manifolds for 5.2 & 5.9 on dodgetrucks.org, dunno if he's still around. Some guys take the stock beer-barrel and clean up the inside with a dremel, they swear they get better torque than the peformance manifolds. Mine's a 2bbl mopar-peformance piece. B&G out of Michigan reflashes the ECUs, but it's expensive, around $400 a pop. I think most of the dak guys go with standalones now. 5.2 & 5.9 TB are the same piece. I've got one that's ported to 52mm by this guy: http://www.thefastman.com/ but a lot of guys just use a dremel.

I put a ton of bucks into my drivetrain, but nothing into the rest of the truck. Did high 14s on stock suspension and bald all-seasons.

In reply to Lesley:

My truck does not have aMagnum engine. It is a two barrel TBI setup. Picture a two-barrel carb with two injectors shooting down the throttle bores. I already have it on an Edelbrock manifold. That is about as good as it gets for manifolds with the stock TBI.

Best a non-Magnum Dakota is going to do with anything resembling the factory setup is mid 15s. Stock for my Dak was 16.5. It is capable of high 15s now and that is with a new intake manifold, better ignition, headers and true dual exhaust.

I'm having trouble opening that one. Try this: http://www.shelby-dodge.com/89-dakota.html

You could stick a magnum in that puppy. That's been done before.
