I took a bone stock 5.9. Added a whiplash cam, intake, headers and a computer tune. Chassis Dyno numbers indicated 360-375 crank HP. ET was 14.2 @ 99 mph with 2.2-2.3 60' times. In a 4,000lb truck

Well, for what it's worth: I went through this a couple of years ago for the 318 in my 5th... Basically, the cost of rebuilding a set of 302's (not easy to find these days) and a set of Magnum heads (easy to find) was about the same here in Cincy. So, Upullandpay for the heads ($100) plus porting it with a set of MP templates that a friend of mine had ($0, just my hours of work) plus a used Crosswind intake ($50 at swap meet). Already had a new set of AMC lifters (same cost as factory lifters- got them from Autozone years ago)...and all I needed was the thin Mr Gasket head gaskets and the MP pushrods- MP 5007477, 7.625" pushrods. This is a sticking point as they are no longer available from MP, so you'll have to dig for them. Added a AVS that I had been using for another (now sold and gone) car. I went with a mild Jeg's cam that is an RV Cam: http://www.jegs.com/i/JEGS+Performance+Products/555/200160/10002/-1The advantage is the Magnum lifters are 1.6 ratio, not 1.5 like the factory heads. So a 'mild' cam can benefit with the larger ratio of lift. Car runs like a champ- added a set of used headers and a 2 1/2 dual exhaust and it pulls like a freight train. Not easy on a big, heavy luxobarge like the 5th. It really needs a higher stall converter, but I'm build a 408 now, so that will wait until the new motor is ready to drop in. Everything you need to know to swap the Magnums- http://www.dippy.org/forum2/index.php?topic=295.0No more complicated than a regular head swap. Might as well get a higher lift and more compression for the same amount of hassle..or at least that was my thinking... Hope this helps, CC.

If you've already made up your mind on replacing your heads with rebuilt heads by Aero, and have closed off the idea of anything else, then why do you keep asking us for ways to pep up the power under the hood for cheap?

a $50-$100 magnum intake for a carb where can they be found? how do we get the fuel to the carb on the cheap with a magnum on this truck? these "little" things add up. the thread says "cheap 318 build" and as per moparts protocol we have the usual build a 360 or go magnum suggestions, soon it will be build hemi. we have ventured way off course here.
lifted85 if you want to swap heads, pull a set of 302 heads from an 85 up to 91 (premagnum) 318 car/truck/van in a junk yard. get a valve lapping tool(suction cup, very cheap), some valve lapping compound(also cheap) and lap the valves. there are videos on how to do this on youtube. its easy. put some 901 springs on using the stock retainers/keepers. call it done. another cheap upgrade, replace the heavy advance spring in the distributer with a light one(think ball point pen thickness) take the heavy spring to a hardware store and match up the length(cost is probably less than a dollar)
Any 318/340/360 four barrel intake will work if the Magnum mounting holes are redrilled and tapped to accept the manifold. I am running a 5.2L magnum I picked up for 50 bucks. On top of it is a Edelbrock 340 intake I paid $100 from a fellow Mopar guy. On it is an Edelbrock 1406 I paid $75 for on Ebay (New in box). $60 Holley electric fuel pump but you can put an eccentric on the front of the magnum to run a mechanical on an LA timing cover. I am running Engine Quest Magnum heads that were ordered with the LA holes tapped into it so I skipped that step but there are many threads on here on how to tap them yourself. Another 125 for a Beauchillon Engineering throttle cable and plate for the torqueflite and gas pedal and that was it. I believe I have less in it than the OP has already spent. The only high ticket item was for the heads. I had already ordered them for the my original 318 but when the magnum engine popped up, I changed direction in a New York minute. Advantages: roller cam so no zinc in oil worries, higher compression ratio (62cc magnum chambers), better breathing in and out, looks just like a 318 and it has more horsepower than the 318 it replaced.

If the 714s have a heart shaped combustion chamber, they are like the 302s. That number sounds vaguely familiar. Later: I did a little websearching and it seems they are brothers to the 302 head. Heart-shaped chambers, use a rocker shaft, 1.78/1.50 valves. No need to use 302s when the 714s are the same head.
And no, they are NOT Magnum heads, at least the type of Magnum that has rockers on studs.

correct 714 casting replaced the 302 casting or vis-versa same swirlport fastburn closed comb chamber small port small valve 318 head. dith the exhaust valve rotators for more guide to retainer clearance with a higher than stock lift cam lobe.

As do used heads, headgasket sets, new pushrods, AMC lifters, etc.
I can get a complete magnum engine for less than a set of heads and gasket set.
Here is one I did not even try hard to find-
http://newhaven.craigslist.org/pts/4417893722.html
"I have a v8 5.2 318 dodge ram motor it runs great no leaks around 120,xxx miles fits 94-01 includes alternator, belt tensioner pulley, a.c compressor, power steering pump, water pump, fan, upper radiator hose, wiring harness, ignition coil, exhaust manifold, cruise controll everything works no problems $300 call"
or a 5.9 for $600 from a yard (there are better prices on these, this one found at random.
http://southcoast.craigslist.org/pts/4423034174.html
"5.9 engine taken out of a 97 dodge ram. has 72,000 miles. engine is complete and ran excellent"
"I think its got a hemi"

Good old fashioned cheap build A set of 1.88 intake heads off a 360
Drops the compression too much, been there and done it.
me too, but the right cam makes up for the low comp ratio
like the whiplash roller cam I stuck in my 91 318, it has short duration/high lift/early intake closing/tight LSA to build cyl pressure and not bleed off torque.
then add a loose TC and some gear the lopo 318 will get with the program.
but it is at a street engine level not a racing engine level of performance.
performance above street level is more $$$ and not so cheap.

My last gas truck was a 82 dodge 1/2 ton ,3.91 gear. I swapped in a bone stock 360 magnum. Removed the injection and ran a M-1 dual plane w/600 Holley. With a full fiberglass rear cap it ran 14.80@94.Doug

thanks 65rbdodge hit it right on, sound's like what i will do. to the other member's i was lookin for a cheap upgrade, the magnum head swap aint cheap, the little thing's add up pretty fast, & why would i pulled a motor that run's good for a magnum?? i just want a little more pep. like i said i wanted some cheap idea's.. & as for the 360, sorry IM NOT A FAN!!! just like some folk's aint a fan of the 318's..

What are 901 springs? Can you elaborate Thanks
