I'm thinking about replacing my V6 (LA) with a V8 (318 LA, carb.).
1) Does the V8 bolt in a V6 4WD car without modifications?
2) I believe I can reuse my starter, motor mounts, alternator, steering pumps and brackets etc., is this correct?
3) Was the V8 cars delivered with stiffer torsion bars than the V6?
4) What is the difference on the brakes for the '88 V6 and '91 V8 cars?
To do this engine swap road legal here in Norway I have to upgrade the car up to the correct V8 specifications regarding springs and brakes.

Carroll Shelby (Shelby Dakota) put one in a flat front style .. first gen is 87-96 i beleive since only real change was the front nose to accomidate more room for the V8 as an option and in my 92 man it had power , also was first year of the magnum
the 318's in the early 90's dakotas will bolt right to the v6 mounts.. i put an 83 318 in my 87 4x4 dakota and had to custom fabricate my motor mounts.. i was almost to the point of going with an elephant ear rather than regular mounts.. but that would have been just as much hassle due to steering box in the way..
The '89 318 should bolt right up to the same mount - supposedly, all LA blocks got the mid-block mounting points by the late 80's in addition to the elephant ears. SUPPOSEDLY.
(IOW - if the motor mounts don't bolt up, then I'm sorry, but it ain't my fault *grins*)
What you can do to make more room is pick up some 1991+ front parts (grill, bumper, core support, frame extensions) and bolt those on. With that, the 318 should fit right in (since those parts were altered to allow factory install of the V8s.)
Past that, V8 wiring and a V8 SMEC/SBEC should take care of most of it.
I'd use the later V8 transmission, or at least get the current one built up.
If you read my first post, if I make the car up to V8 spec I can get the car modification approved. We do have emission laws, but they're not very strict. Even the exhaust catalytics wasn't required before '89, which makes my '88 clear those rules. We also have to pass a technical inspection every two years. For the engine upgrade I'm doing to this car there will be a separate technical inspection focusing on the parts that has been replaced/upgraded.
What we do have is taxes based on emissions, which makes US cars expensive to import to Norway.
1 liter of 95 octane (equal to yours 91) is $2.5, or $9.45 per gallon. Compared to what money we make, it's not that bad.
