76dodgeboy OP master Joined: Aug 2006 Posts: 8,064 Iowa	My brother in law has a 62 Valiant and we've been going back and forth on what powerplant to put in it. Just to put an LA318 requires ditching the heaterbox and other cutting. It finally came to me last night. A 3.9 V6 5spd from a Dakota. Most likely a magnum. What has to be taken from the doner vehicle and how hard would it be to wire it to the car if we can find a doner cheap enough. Thanks

You can get some pretty good kick out of them with a little work, and even upgraded would likely be cheaper when your all done then a 3.9 swap will be. To put a 3.9 in there, you will need at least, the motor, trans, wiring, computer, fuel tank (or at least the proper pressure pump), motor mounts, exhaust, and probably a rad. Then, the exhaust manifolds might not fit in the car (they are rear dump), the steering column may not clear the motor, and you will likely have to modify the firewall and trans mount areas. I suspect the 5 speed shifter is going to be in the dash as well, they are built into the top of the trans (like a granny gear 4 speed). A 3.9 motor mounts are at the center of the block and the 225 are more towards the front, I have to wonder what your going to have to do with the K member. A 3.9 is as wide as a la 318, and only 4" shorter. Do some measuring. Gene

There is alot of power that can be had in a /6. Try taking a look at Clifford Perfomance's site. Turbo /6? 70 'cuda: ProCharged 408, Tremec 5 speed, S60,triangulated 4 link, Hydroboost and Wilwoods

Plus its not cheap to hop up a slant unless you find bargins witch are getting scarce. The 3.9 can be mounted forward some. People have installed V8s in them so it would be slightly easier with a V6 and rear dump manifols would imo would be best. The shifter lever can be modified to fit. I think a wrecked Dakota can be had for $350 or less and thats cheaper than a 390 Holley 4bbl so price wise is a very gray area do to not knowing what a wrecked truck can be had for and I think it would be a great gas mizing cruiser

Finding mag 3.9 5 speeds around here would be a challenge with anything less then 200k miles, then they would probably want $1,000 for a beat to death one. Hope you rate better in your area. Gene

When you spend the same money on the 3.9, you still have to make it fit in the car. Just saying.... Wonder what the power numbers look like between the dressed up /6 and the box stock mag 3.9? Us Mopar guys never were much worried about doing things the simple way, it was always the final outcome we were concerned about. Swap in the 3.9, take a bunch of pictures, write up the "how to" and show us the track results. We are all waiting. Gene

With the slant six introduced in 1960 in two versions, a 101 hp, 170 cu.in and a 145hp, 225 cu. in. version, the slant six built its reputation for performance and reliability. Hyper-Pak specs: �Overhead valve. Cast iron block. �Compression ratio: 11.5:1 (225), 10.5:1 (170) �Brake hp: 195 at 5200 rpm (225), 148 (170) The Magnum versions, with multiple-port injection, were rated at 180 hp. Torque jumped from 195 to 220 lb-ft as well You can get a bigger trottle body and injectors but Im sure he can find a Dakota for Under $600 and the weight difference is Valiant 2750# and a regular cab shortbed Dakota is 3042#. Wich would improve milage imo. He might not ever do it so dont plan on a build post.Plus he dont have the skills needed but I think I might If he does go through with it Ill deff post about it.

It wont be that hard if he can find a whole truck for the swap, than he would have all engine related parts. "IF" he does move forward on the swap we will have to look further into the centerlink. What els had the 3.9 other than the Dakota, Full size trucks and Vans? Might be able to mount it back enough to clear? I havent really look at the car to even get a feel for what would have to be done. Plus using a 3.9 if he decided to rebuild for power reasons it has the same cylinder bore as a 318 and he could get some good used higher comp pistons or if money is available a supercharger (procharger) or turbo it. Remember thier will be a bit of room front and back of the motor since it is shorter buy 3 cylinders

Usually, the full size trucks & vans are cheaper then Dakotas because the big stuff with a 3.9 was underpowered and resale value was low. Probably be easier to find a low milage full size truck with low miles cheap. Gene

That needs further looking into Thanks If the 3.9 has the same oil pump as the 5.2 I think we could modify the 3.9 pan with a car pan tht will fit the 62 better. Like Ive said though. I havent looked at the slant in there to see what it could or might need done. Might not have to do anything.

You may be able to mount the 3.9 far enough forward to only need a notch in the back of the pan to clear the centerlink. have pondered this swap for my 65 Cuda. If you mount the 3.9 as far forward as you can that opens up more real estate under the floor pan for the 4sp auto most of them are hooked to. Early A's require severe butchery to put a 4sp auto into one. Moving the V6 forwar as much as possible will not only give you more distributor to firewall clearance (62 A will need that) but it will remove most of the trans to tunnel interference issues. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Basically I would make a 3.9 Car pan is what I ment. It all depends. I havent looked at the bay of his car yet.Bang for buck its WAY cheaper than building the slant up to even meat the 3.9 Mag stock hp we could just stuff a Grand National motor in it NOT. I think itll be a fun build aslong as he want to actually do it and not just bs about doing it. I really want to help he do it

Yeah, I know it is almost a year later but I was curious as to what became or what choice of power plant you decided on for the '62 Valiant ? The V8 choice is not difficult. I am currently running a 360 in my '62 Valiant wagon WITH a heater box still in place. Just trimmed and boxed in an area for the distributor to live in. Email me at: chargeray@aol.com I would be happy to share knowledge with you or anybody interested. Ray G.

Or it can be a great learning experience... Just saying. So long as someone is willing to help fund the project. I knew a kid in high school who had his dad restore his 66 Mustang Conv. Basically whatever he payed for the car, his parents would match it. I think it's done being restored but I think he should have pulled a wrench or two. And it looks like such a girl's car. Not masculine at all.

I'd ditch the 3.9 liter engine idea, that's about the most craptastic engine you could pick. Seriously. They are still dog slow and the mileage sucks. It may look good on paper but they just plain suck. Even Poly 318s make fun of the 3.9. I'd go 360 or 440.
