   I accept a bone stock 318 in my 74 dodge sprint that I want to beefiness upwards a bit. I will admit right at present im a cheap ass and dont want to sink a fortune in this affair. With that being said, what can I do for cheap/free? It already has dual exhaust with no cat. are headers worth information technology? dont know if its 2bbl or 4bbl, but mayhap bigger carb (is the 2 to 4bbl upgrade cheap?) what nearly removing the smog pump and a/c? ar advance the ignition timing? bypass fan clutch? Im new to mopars so forgive the newb questions

   I besides have a 318 dodge dart sport, but i spent more $$$$$ on it then you are willing to do. Every bit far as the headers being worth it, i will say yes, but exist prepared to go through hell kickoff. Putting headers on my dart sport was a nightmare, i learned alot from the good people on this site, dont get whatever bigger than a 600 carb. good luck

   First of all welcome!

   Every bit for your 318;Information technology will exist a two bbl unless someone already changed it. The cheapest upgrade to 4 bbl would be a cast iron stock intake and a thermoquad carb. Lots around on 360 powered trucks/vans and some 80's era 318 cop cars (Diplomats etc).Some late 80'due south 318'due south had rochesters likewise and a skilful casting caput called the 302. Brand sure to get a 4 bbl air cleaner filter and housing. A K&Northward air filter is inexpensive,and reusable.

   Dont carp upgrading your ignition system. Not much gain per dollar there.

   Height offers inexpensive headers,dual exhaust kits and cams. Your mopar is an A body. And yeah it'southward fair amount of piece of work to install headers. If you modify the cam,exercise the timing chain. Upgrade it to at least a double roller. For a few more bucks y'all could add together a tensioner. Wont help brand ability but volition ensure authentic cam timing when the concatenation starts stretching.

   Another cheap upgrade would be a thinner head gasket. Buy an .028 thick Mr Gasket head gasket. A bit more compression volition assist.

   Transmission shift kits are inexpensive as well and simple to install.

   A distributor recurve kit is some other cheap upgrade that volition help. Or grab a used one from a modest cake pickup/van. It will have a fleck faster advance curve and lighter springs.

   If you tin can port and accept the tools,that will definitely help quite a fleck and cost you almost nothing.

   Rear gears would really assist,but probably be more expensive than the other mods and I have no idea what you accept for gears/unequal.

   Adept luck!

   What is your greenbacks limit/ spending limit? A "Fortune" is a realitive term.Not much.In the long run, yes, when hunting for power.Realitivelyremoving the smog and A/C pumps volition complimentary HP that is allready at that place. It's called parasidic loss. Or when you become rid of the pumps, gain.
   You lot can not "By pass" the fan clutch, but you can do i of ii things.
   Get a viscous fan from MoPar which uses less power or got to a electric fan and rid yourself of parasidic ability loss.

   For tips, read through my thread which is more about getting the old heap upwards and running and then adding power in a spirted style called, "On the Cheap", which is once again, realitive to what's in your pocket.

   In short, I took a bone stock 1979 - 318 and added a 4bbl. & intake, headers, cam and matched springs and a electric fan. The car has a auto trans and 3.21 gears on stock tires. At ATCO raceway N.J. on a cold cold day, untuned it ran 15.14 @ 89 mph.
   Cheque the classifieds here for intakes and carbs etc.... on the inexpensive.

   Farther functioning can be had cheaply with milling the heads. Toll for this varies widely. I had a gear up milled down for $35 and some tin't believe it. I run into others pay triple per head.

   Advancing the ignition will help, but you can go to far.

   A simple air cleaner from the local motorcar store will help.

   A MSD ingnition will clean up and ignition issues and will put some mileage in your tank. IMO, this is a worth while thing to do.

   IMO, this kit which is preety complete as far every bit I tin tell is a nice package.
   Once I had this in hand, I'd port the heads with ane.88 and 1.60 valves (360 valves) and be set up for a good street runner. This should make a piece of cake 350 HP. But cheap is realitive.

   cheap to me is less than 400$ in the whole projection. then yep prolly wont be doing the heads. the 4 bbl carb and intake sound similar my best option at this point. I call up I may even have a 4bbl holley laying around somewhere

9. $400? If it were mine I would spend information technology like this:

   Cheapo headers ($100), used eddie performer intake ($l-$75), used Gluey fan ($50), a rebuild kit for that carb you lot have ($20?) Lighter springs for your distributor ($xx?) and some decent gears. Buy actually proficient header gaskets or double them up considering those cheapo headers will probably leak. This is exactly what I did with the old stock 318 in my Squeegee. My gear pick was .410'due south. I have the machine on stands now in the garage. It is getting a new 340 and 904 in information technology, but the melted rubber from the "stock" 318 is even so splattered all over my quarter panels.:thumbrig:

   Yous will recollect you have a unlike car.

   If more was in the budget I would go a unlike way, but if I only had the $400 this is what I would exercise for simple inexpensive upgrades.

   This should get you your "prepare" for a year or so. In that twelvemonth, I would attempt and choice up a used 360 (or 318 if you prefer) and built it a slice at a fourth dimension with adept parts. When the 318 is prepare for a rebuild you lot tin can just swap in your new motor and your car is only down for a day.

   You can even use all the parts y'all bought for the sometime motor on the new 1. I would endeavor to get a little better headers on the new engine though.

    Your shut to screwed, the abpove proposition is a adept one. The headers from Summit or Jegs @ something like $99 and stop it up with a pair of 4ft. directly pipe @ 2-i/iv inch and a pair of top or Thrush turbo mufflers. There very inexpensive. Y'all'll probably need 8 clamps and two hangers. Arrangement ends in front of the rear axle. Exhaust gaskets should be Mr. Gasket Ultra seals. Very good stuff.

    The above mentioned used intake and carb might be found here or at a bandy encounter. Carter carbs are easiest to rebuild.

    On a gear change, you'll spend nigh $400 on parts nevermind the installation of them.

    So far on my gear change in my eight 1/iv for my M torso, I bought a decent set of used 3:55 gears. $120. Deceit imagine spending some other $280 to install them myself...

    I had no thought the factory head gaskets were .028 thick. Mr gasket does sell thinner ones.

    Agreed on the headers. I spent $50 on my used set,which havent even been run,but trial fitted and bashed a bit. They look just like hedmans. Y'all will demand header bolts also as gaskets,again cheap.

    A cast iron intake should be cheaper than whatsoever aluminum intake and they are actually a very good piece. it'southward unlikely you lot'll encounter cracks or stripped holes. If it's spread bore,information technology'll commodities right on. Dont pay more than than $25.

    I still thnik gears would give yous the most bang for cadet in the acceleration section,IF yous can become a good used fix for cheap.

    On the real cheap ? A real good tune up, Cap, wires, plugs and filters.

    Advance the timing to 10* before TDC, Summit racing has headers for $100. Option upward a used Performer intake, Probably around $100. Then hunt for a cheap edelbrock 500 or 600cfm carb.

    Are you sure that stock head gasket is that thin? The source material I have says .xl or thicker?

16. 

    rumblefish360 I have escaped the evil Empire State! FABO Gilded Member

    Aye, very sure. OE head gaskets are the aforementioned one found in the MP parts catolog as there listed @ .22 - .028 thick.

    Any gasket after that is aftermarket and the Fel-Pro'south I normally run into are .039.

    Tin can you send me the link for this kit? I click the link and it won't open

18. For $400? Melody up, get your timing dialed, exhaust exactly as mentioned past rumblefish. Jegs has pretty squeamish copper gasket for the headers, best $31 you'll ever spend if you rock headers with a five/sixteen" badly bead ground warp chief flange (like top or jegs headers, which I like and run.

    It becomes dead after people end posting in it and that is oft later several years it gets called dead.

    That link is very sometime and seen many many times. It's erstwhile news except to new eyes. It is easily found here and on the goggle search engine.
