Was there ever a continuation for Doug Dutra's slant six fuel rail article? Also I'm trying to locate info on the correct throttle kick down adjustments. I'm new to the slant six world and intrigued with the possibilities. I recently purchased a fairly clean 64 Dart w/ an 170ci. I also picked up an 2bbl exhaust manifold, in hopes of installing a "super six" set up because it seems quite slow out of the box (compared to a 66 Dart w/ a 225 I had prior). Thanks! |

The '73-up exhaust manifolds are all the same, 1bbl or 2bbl, and they have the correct choke pocket for use with the 2bbl choke thermostat. You'll need the 2bbl intake, carburetor, air cleaner, complete linkage and bracket assembly (including the actual kickdown lever on the transmission itself), cable-type accelerator and correct short throttle cable. Your stock 1bbl kickdown linkage is simple to adjust. Directly in front of the firewall, where the throttle rod emerges, there is a vertical rod that runs down to a bellcrank bracket bolted to the floorpan/firewall. The top of this rod is threaded, a ball socket is screwed onto it, and this ball socket is snapped onto a matching ball on the rear of the throttle rod bellcrank (the other ear of the bell crank has the throttle return spring hooked to it). To adjust your kickdown linkage, unsnap the ball socket from the bellcrank ball. To make upshifts later/harder and downshifts earlier, unscrew the ball socket (which makes the rod longer). To make upshifts earlier/softer and downshifts later, screw the ball socket farther down onto the rod. Don't go too far in either direction. If you get the rod too short, the trans will short-shift 1-2-3 at very low road speeds and you won't have kickdown. If you get the rod too long, the engine won't return to idle because the kickdown linkage will hold the throttle open. With a 170/auto a good general starting point is to have the 1-2 shift occur at approximately 9-10 mph and the 2-3 at approximately 16-17 mph when the throttle is pressed in a moderate manner such as you would use when the light turns green on a 45mph road. I don't think there was ever a continuation of Doug's fuel rail article, but there have been others, such as This one and This one. |

Dan, You mentioned "including the actual kickdown lever on the transmission itself" for the Super Six conversion. Can you describe the difference between the two? Aaron and I just finished installing all the throttle, kickdown, and shift linkages for his '74 Dart Sport, yesterday. The lever on his 904 is the same one from his original stock 1bbl setup. Now, it sounds like we need to find another piece of the puzzle.  Jerry |

The 1bbl kickdown lever is longer than the 2bbl kickdown lever. The 2bbl kickdown rod will attach to the longer 1bbl kickdown lever, but you won't be able to get an adjustment that will give correct upshift speeds and correct kickdown. |

Dan. thanks for the info. Does anyone have any idea of a good salvage yard to find super six parts (I need a 2bbl intake, throttle cable and kick down linkage). I'm in the midwest and tried about 30 yards to no avail. Thanks, Dale |

www.car-part.com , searchable used auto parts clear across North America. Put in a search for an intake manifold, '78 Dodge Aspen. You can confine your search to whatever geographic area or individual state you want. Next screen, specify 225-2bc (2 barrel carburetor). Results will come up, and it's a fairly good bet that places showing the intake also have the rest of the car. |

Thanks for the info! This slant six world is very responsive and freindly I'm glad to be on board. |
