One that fits under the hood and clears all the linkages. Aftermarket open element units are available, but they're noisy. I prefer to junkyard dive for OEM type air cleaners. -You'll need a transmission kickdown linkage (I'd get the complete assembly, including throttle cable and the bracket that mounts to the manifold. A good donor is a 4-bbl Diplomat or Gran Fury copcar. Failing that, you can get a Lockar kickdown cable kit. - You'll need fuel line. Use either a hard line or FUEL INJECTION hose. Do not make a long run out of regular "fuel line" hose sold at part stores- if you're going to run that much rubber line use fuel injection rated hose. |

A 4-bbl and dual exhaust (don't forget the crossover!) are a nice mild wake-up for a 318. To take full advantage of headers, you'd really need a bigger than stock cam and exhaust port work. Headers won't HURT, but put your money elsewhere first. |

After the install,if you cannot adjust the kickdown linkage properly yourself, tow, do not drive, your car to a transmission shop and have them do it. It MUST be adjusted properly. See also: http://www.edelbrock.com/automotive/eps_intro.html for carb tuning information. You may need a PCV valve for a 4BBL 318, from an early 80's 318 4BBL cop car.(maybe a different hose also) How about the choke? Is it electric? If so, don't tap into the ignition coil to drive it. (A common mistake.) Speaking of which, convert to an electronic ignition if you can afford it. Here's some wiring info: http://www.225.ca/tech/images/js005.jpg (I2 is start, I1 is run) Junkyard parts will be cheaper. (control box, wiring harness, coil and distributor ) use a new ballast resistor Does the old carb have an idle solenoid for A/C? You may need to do a little rigging for that. Make sure all the old vacuum lines are connected to the proper vacuum types, i.e. ported or direct. A can of carb cleaner to check for vacuum leaks. New thermostat, housing, gasket and coolant? If possible, use washers under the manifold to head bolts if the bolts don't have a flange. Aluminum tears easily. HTH -- Steve Walker (remove wallet to reply) |

I like stainless, but always use anti-seize with stainless hardware. nate -- replace "fly" with "com" to reply. http://home.comcast.net/~njnagel |

Steve, Wasn't there a 340 cid engine available about that time which was essentially the 318 punched out? Seems that I helped a friend swap a 340 in place of his 318 in a Duster, but may be confused. I know for sure he installed a 4 barrel on it. With all the modifications he eventually performed, this project evolved to a monster. He could lift the front wheels off the ground - seriously- in low gear. |

It was rated at 275 BHP and with a little tweaking could put out a lot more than that. I believe that manifolds, and many other parts interchange with the 318. |

Original intake and exhaust manifolds are rarer than hens teeth, (read, pricey). Yes, parts will interchange, the intake manifold will fit but there will be a severe port mis-match, exhaust manifolds off of a 71-72 C-body 360 will fit the 318 and flow a lot better than the 318 manifolds. 360 "J" heads flow as well as the 340 heads and are still found in salvage yards, one needs to be careful with them on a 318 WRT valve size, too big of valve and you have shrouding problems with the cylinder wall. And no, the 340 wasn't a punched out 318 any more than a Chebby 350 is/was a punched out 265. |

"aarcuda69062" > wrote in message ... > And no, the 340 wasn't a punched out 318 any more than a Chebby > 350 is/was a punched out 265. Would look like basically a bore job. Stroke was 3.31, bore was 3.91 on the 318 and 4.04 on the 340. 318 (5.2) 1967-2002 3.31 3.91 340 1968-73 3.31 4.04 What are the other differences, Aarcuda? |
