I had read an article a good while back in Mopar Muscle magazine, it was an article about doing a build on a 318.
The article started out by stating that "if you have a 318 and want more horsepower, get a 360. If you want more Torque, get a 360. If you want more of both get a 360. If you want more options on performance parts, get a 360. But if you just have to absolutely have to upgrade you 318 here's what you do."
Then the article went on to give part numbers and mopar performance stage kits. Seems to me that a 360 would be the way to go IMO.

bad news guys. last night this retard in a lifted 4x4 chevy on 35s with a 1/4" plate rear bumper stopped in front of me. The he saw a parking spot at the bar and proceeded to back up and crunch my hood, grille, rad support, headlights, bezels, a/c condenser, and to push the rad into the fan. I think it is a writeoff. the truck isnt in great shape and has a lot of miles on it. Sucks because the night before I strted makeing the shaker scoop for it. Good news is I found a 1969 dodge 4x4 with a 318 and a 4spd I might get. gonna have to wait and see how things pan out. Have to wait till monday to talk to insurance company.

hey gen 1 dak i am looking at a fullsize dodge with a 360 in it. What setup would give me the most power and low end torque. same as 318 but with a different cam? what kind of figures would I be looking at? You are the most knowlegdable person i have come across so far so i figured it would be best to ask for your suggestions. thank you

Thanks Zac. Glad to help out where I can. The 360 responds to the same mods we've talked about for the 318. Since both engines, despite the difference in displacement, manage just over 400hp with the same heads (all else being equal), that says a lot right there. Naturally, with identical setups, the 360 will have a fatter torque curve below 3,000rpm. To take advantage of the larger 360 for HP, you need better heads, but for street duty I wouldn't go nuts here. A nice port and polish on 360 heads with 1.88 intake valves will easily top 350hp with the CC268XE cam, 750+ carb, Performer RPM AirGap intake, good exhaust. With the 2.02 intake valves, 400hp is a no-sweat deal. Torque? Fuggitabouddiittt. Get a neck brace. The longer stroke of the 360 really helps down low, but it'll still easily rev through 6 grand. Just remember that something in the XE 268 is gonna be pretty much the hottest cam for street duty. Any hotter and you'd need to look at beefing up the bottom-end, and it's not be the best for cruisin' a full-size. With the 360's extra low-end grunt, you could run with the stock converter, though, naturally, a slightly looser one always helps off the line. I kinda had a feeling you'd go full-size. Lately I've been messing with a RamCharger. Can't help but love those big tanks. If you wanted to step back a bit with a nod towards gas mileage, even a "smogger" 360 with 8.5:1 CR managed 335HP with the XE256 cam. That was with the somewhat restrictive (for a 360) standard Performer intake. You could easily make more power with the stock cast iron 360 4V intake over an unmodified standard Performer. The Air Gap smokes 'em all. Still, especially with street cams, the stocker intake gives a good accounting and it's dirt cheap and legal everywhere. Plus, all your accessories and brackets fit as intended. Spend the cash on some other part (like a new high volume oil pump and HD distributor drive). You can always change intakes later. Set the timing for around 34 degrees total and hang on. Mopar's crate 360 (rated at 380hp, but actually making over 400!) puts Dodge Dusters deep into the low 12's. That's a wicked engine, not what you'd want in a street truck, but it just gives an idea of what a 360 can do.

its a 4spd so no converter troubles. what kind of torque numbers would you imagine? Its also a 4x4 so i dont want to lose hardly any low end torque.

Well, let's look at the pre-Magnum 360 Commando crate engine. This is essentially a production 360 LA engine with high vol. oil pump, MP cam (268/272 gross duration, .450/.455 lift), dual plane M1 intake, 1.88/1.60 valves (stock heads), 600 cfm carb. This engine produces 300hp at 5250rpm with over 300 ft-lbs torque available from 2250-5250rpm. The Super Commando 360 had the same cam, but has 2.02/1.60 valves, and a single plane M1 intake. With a 750 carb, it kicks out over 360HP at 5500rpm, and maintains 365 lbs torque from 2250-5750rpm. So, factor in the better cams that are available now, as well as the AirGap intake, and you can see where you'd easily be able to make a stout engine with a broad torque curve in the 350 lbs range over almost the entire rpm range. Keep in mind that if these LA heads get a good port/polish job, you'll easily bump up another 30 lbs torque over un-modified heads.

I'm guessing we're talking about an LA 360 vehicle. Is it, or does it have a Magnum?

yes it is a LA 360. Its an 85 fullsize 4x4 4spd. What year did they start putting the roller cam in them? Also do you know what axles were in trucks of that year, and when they went to the CAD(central axle disconnect) style? I think it is 85 but i am not sure.

Mopar began use of roller cams in the 318-powered cars in 1985. Typically, anything they introduced on the 318 came a year or so later on the 360. These changes were phased in, so sometimes it's hard to pin down just exactly when something hit the line, but yours is most likely a flat tappet cam. Some 318 tuck engines came with flat tappet cams, but had the holes drilled for the "spider" that were required to hold the roller tappet yokes in place. Not a big loss. A modern "black" moly-coated flat tappet cam slicker than the old non-coated ones.
The primary axles, as I understand it (not as well-versed in 4x4, but getting more into it with my RC dealings), in the front were the Spicer 44 and Spicer 60. The Spicer 60 was used in the heavier setups, meaning 3/4 ton units with a special suspension package, and all 1-ton units. The rears varied from the 8 3/8 to 9 1/4, 8 3/4, Spicer 60, 60HD, and 70. Now, being an '85, you won't have the 8 3/4. Being a 4x4, you won't have the 8 3/8. So, you have either one of the Spicers, or the corporate 9 1/4 rear.
On the CAD, not sure when they came along. I should also point you towards the ramchargercentral.com website. Tons of info, including locking of the CAD. You'll see me in the forum under the same name.

This was posted in 2002, so I suppose the CAD is still the method of choice.

thanks. thats when i thought it started but had no idea it was still in use. have you heard of any cheap ways to lift the front of a fullsize? to accompany the RCC hanger and shackle flip.

I was wondering if they make 1.6 rockers, roller or not for the LA engines. I figured it would help out until i could do the cam. I would get some other heads and get them ported and polished and install the rockers, intake,and heads at the same time.

I haven't seen non-roller 1.6 rockers for the LA's, but they do make roller 1.6's. Occasionally see some on eBay. Also Harland Sharp and Crane, others as well.

Generally, the 1.6 rollers add 15-20HP due to a combination of increased ratio and a savings in frictional loss. So, maybe 30ish with some porting.

Ummmm, standard? Not sure on that, but in my experience, the 360 2V hasn't been nearly as numerous as the 360 4V. HP was so slim, most opted for the 4V to get every little bit extra they could. I just picked up a clean Thermoquad from an '81 Dodge van with a 360. I'll have something to put it on eventually. Gotta love that 800cfm!Thermoquads were used through the mid-80's, but the last couple years before fuel injection, Carter wasn't able to maintain production and Mopar had to use the Rochester Quadrajet.

are the Thermoquads very good for off road like inclines, declines, and sidehill situations. i dont plan on any regular extreme wheeling mostly trails and mud but i would like to be able to try more extreme situations if the oppurtunity presented itself. What were the 360 4 barrels rated at around 1985. HP and tq?
