Wow, great information. If I can find the magnum, what do I need to do to switch from EFI to carb? Any idea on cost? Thanks.

We're at the horsepower wars again! I maintain a 318 with a medium sized four barrel carb and dual exhaust, using 360 pickup truck manifolds or whatever'll fit, is the ticket to get this rig on the road. If you want a little more power swap in a 360 cam at the same time, will be a good starter motor. It should make around 250 hp which is plenty to keep a 3000 or less pound pickup going down the road. Yes, there are plenty of options. Bt they will all be worthless until you actually start driving the pickup! I speak from experience. I have started plenty of projects by building an engine and have yet to drive most of them, although the engines look nice hanging on motor stands! R.

I've got my uncle's old '86 D100. 318 that he added a MP cam(one step above stock) and intake, Eddy 4 barrel. dual exhaust. It's no big block by any means, but it sure runs better than any other 318 I ever had.
agre with the 360 being overworked in the MH, and the hassel with having to scrap the remains.

The cost depends on whether you use the original serpentine Mag stuff or 78back LA V belt drive
The V list is as follows
Crosswinds intake $180.00
Cam snout extension 23.00
LA timing cover,Brackets & pulleys/fuel pump
Serpentine list
Edelbrock RPM Air-Gap $322.50
Carter 4070 Electric fuel pump $78.00
The Crosswinds is a direct bolt on with a RV2 compressor brackets
The Edelbrock needs spacers made & different bolts to attach A/C brace & Alt brace
I own both
Most of that stuff is not needed. You can redrill your heads to accept any LA intake manifold. The angle the intake bolts go in is different. Or you can buy one of the intakes on the market that will fit the magnum heads and take a carb. Those are a little more spendy at around 300 bucks. Don't need the LA timing cover, brakets and all that stuff unless you want it for looks. To run the serpentine stuff I just junked the AC compressor and bought a belt for a non-ac 3.9 magnum truck. I had to slightly reposition the tensioner but no big deal. No cam snout extension needed, buy an electric fuel pump which I much prefer to run instead of a mechanical one anyway. If you can do a little bit of wiring and can find a 92-95 dodge truck/ram van at the junkyard you can snag the engine harness and computer out of it and even keep the efi. This way no changes to the engine are needed. My donor engine is out of a 99 dakota but I grabbed the electronics from a 95 because they're easy to swap in.

I'm looking at doing the same swap in a '69 B body, the Magnum motor sounds perfect. I do have a couple other questions though.
First, what motor mounts would you need, the stockers (that need replaced anyways) or something different?
I was planning on using the stock 904 and converter, any issues?
And this is an AC car. If I find a motor with the AC condenser on it
would that make it remotely possible to go with an R134 set up (If I snag the expansion valve and drier, etc..). I guess I'm asking if the old evaporator and condenser would work with the new spinnin parts??
Thanks!

Magnums still have the old LA style mounting ears on them so they will accept stock motor mounts. I don't see any reason your old evaporator and condensor couldn't be reused with the magnum compressor. The expansion valve system is likely different because I don't think the newer ones use the valve on the evaporator like the old ones and I don't know enough about them to make a suggestion on that. Biggest challenge would probably be having custom hoses made to mate everything together.

What is the end goal aside from a summer driver right now? Do you see yourself tearing back into this for upgrades? If this is going to be a do-it-once-and-forget-about-it project, then Magnum all the way. Pound for pound, you're going to get better mileage and power from one when compared to a similarly built LA.
If it were me, I'd find a 318 Magnum, freshen it up while keeping the stock internals and drive it. Just a 4bbl and headers on one of these will put you around 250 horses.
If this an evolving project, drop the LA 318 into it for now and enjoy.

Depends what you want, but yeah, the 360 will feel stronger. At the end of the day, 42 cu in is 42 cu in and there really IS no replacement for displacement.

 If you want to go with a mid-90's magnum small block, I'd look for a 360. My old 1994 Ram with a 360 was more than half a second quicker in the quarter than a same-year 318 even though it only had ten more peak hp.

I would have to agree, however I found it much harder to find a 360, especially if it was one I wanted to hear running first. I ended up finding a guy parting out a dakota that was still running and half way complete so I went for that. Some say the mag 360's are notably heavier on fuel, others say they're very close. In the end even the mag 318 is going to have more power than an old LA 360.

well, a 318 magnum with bolt ons will push a 2ED dakota to low 14's, maybe even nip the 13's...my old '96 ram 2WD long bed, at 4700 lbs plus my 230lb butt in it pulled low 16's and all I had was a cat back, MP computer, and 14" open element air cleaner. similarly equipped 360/auto 4x4 rams were mid-upper 16's, and extended cab 360/auto 4x4's were low 17's....
my dad traded in his '97 regular cab 4x4 with a 318 for a '01 extended cab with a 360 and regretted it. didn't pull his boat any better, but he went from 19-20mpg highway and 15-16 mixed to 15-16 highway and 12 mixed.
for a cruiser, a magnum 318 will have more than enough power (about the same as an LA360) but significantly better fuel economy. and magnum 318's are a lot easier and cheaper to find than 360 magnums.

"enough power" is highly subjective; "enough" for you might be nowhere near enough for someone else. In any case, all things being equal (LA318 to LA360 or magnum 318 to magnum 360) the additional 42 cubes is noticable and yes, I've had both.
Dave
If a magnum 318 isn't "enough" power for your drive, IMO the mag 360 won't be either. There is a difference in power, but not that dramatic. We're not talking 100hp/torq increase.

now it's a definition of "dramatic"!  yep, you're right, only 10-15%. whether that's "a little", "a lot", "noticable", "worthwhile" or "dramatic" depends on your perspective. 
I'm just saying that everything else being equal, I'll go with the 360 over a 318 just like I'll take a 440 over a 383.
None of those are particularly expensive or hard to come by.

GO with the 318 and get the car motivating, then if you want more power take your time and find the right engine and build it the way you want!
