3500 for a bulletproof trans, or LS swap?

Got a dodge dakota with a 5.9 that I want to put some heads/intake/cam on, maybe eventually a blower. I have heads/intake already. Truck needs a new trans. There's a reputable shop that builds a nice 46re (up to 750hp) for 2500 plus about 1000 for installation, putting me at 3500 for the trans. Then I will probably be about 1000 into a new cam, lifters, springs, throttle body, tune, getting me to maybe 340hp/380tq.

My question is, is it more logical to put the 4500 towards an LS/LQ swap? Being in California I would have to deal with making it CARB legal, pretty sure exhaust wouldn't be an issue, but not sure if fuel tank needs to be swapped as well. Will be a bigger project, but a 6.0 is a better platform.

Kind of torn on this, would like to keep it MOPAR but want to be stupid with my money

Thanks

It looks like you can save a bunch of money if you keep things simple. For one, it looks like you'd be putting more money into a trans thats over built for your engine build (46RE built up to 750hp for a 340hp 5.9) A 46RE can handle 340hp. So if it were me, I'd look for a 46RE thats either in usable shape or do a basic rebuild maybe add some small upgrades but not a lot. Next $1000 to install a transmission seems a bit high. I would do the installation myself and save that money for something else.

An LS swap is totally up to you. I do not live in Ca. but as I understand it, it's going to be difficult to comply with CARB which seems to get more restrictive every year. All I can suggest is do your homework and talk to those who specialize in LS swaps in your state to get the low down on all the legalities. Personally I think it can cost you more than $4500 to successfully swap the LS. Expect some hidden costs.

$/horsepower LS is the only platform that makes sense. That said, if the budget is 4500 then the rebuilt 46re with some tweaks to the magum motor is the way to go. Scratch the blower Idea.

Strip out the 5.9 and sell it to some fool whom owns a TJ, and tell him how easy that would be.... then sell whatever is leftover from the Dakota and be happy it's gone.

Then... take the profits from above sales, and the 4500 you already were ready to spend, and go buy a GM vehicle. Done.

Sounds like he's not ready to suck dick, just wants to put it in his mouth.

$1000 to install a tranny? Buy a case of beer and have a buddy with a transmission jack come over. For someone who knows what they are doing this is a couple hour job. For someone with only a basic understanding it might be a weekend job.

As others have said, a 750hp rated tranny is overkill. If you are on a tight budget, get a basic rebuild and spend your money elsewhere.

If you are thinking about spending $1000 to have a tranny swapped, you are not ready for an LS swap. I am not a purist by any means but why would you want a LS when you can get 340hp out of your current engine? Yes it is cheaper and easier to get power out of a Chevy, but for the money you are spending to put a Chevy in your Dodge, you can build quite a bit of power from your 360.

Now for the best advice of all:
Take your $4500 and spend it on moving out of Commifornia. Just make sure you don't bring socialism with you to a free state. Then you actually get to keep more of your money, and with a cheaper cost of living combined with no CARB, you can build what you want for less money much easier.

I'm very attached to the Dakota platform, so that's staying.. I got a nice cowl hood, Hotchkis, and some other goodies. I've had Dakotas since 2003, and have grown very sentimental to them.

I have Magnum R/T heads, M1 intake 92/93 dakota manifolds (larger collector), a Hughes cam, and a flashed ECU (which I doubt I'll be able to reuse since its from a 5.2) from my old setup.. that had a 44re and it handled burnouts, 4x4, and drag strip without as much as a fluid change. 46re seems to bring the suck. I just figured it will cost me at least 1000 to get whatever I need to put the parts in my new truck, plus the tranny.

My reason for wanting to go LS is cheap transmissions and better MPG. 11.5 MPG brings teh suck.

The 750hp 46re is basically his standard build. I called some local shops, and they want about 2k for a regular rebuilt trans. The 46re in the truck was rebuilt about 50k ago (I wasn't the owner back then) and has been having issues shortly after the build, so I don't mind paying extra for something that will last.


I was being lazy about swapping it myself, maybe I am getting older and tired, but if you folks say 1k is too much, then I guess a weekend of work is in order. I have watched videos on rebuilding a 46re, but transmissions are foreign to me, and if I go through the work and end up needing to redo something, I will hate having to do all that work again, so I don't mind paying to get it right.

Sounds like paying for the trans and swapping myself is the idea. LS swaps seem easy, but yes I do live in California and no idea what would be needed to make it legal.

Thanks!
