    Stuck Correct Key- Wont return to release position

    As noted, the shifter/column lock front rod in your floor shift 1970 Challenger may need adjustment: After the shifter linkage itself is adjusted to match the transmission internal detents, the column lock is set with the shifter in park by rotating the column section inside the car to allow...

    Thermoquad questions

    The secondary link adjustment is for when the secondary throttle plates open in relation to the primary throttle plates' position. At any primary position less than that point, the secondaries should be fully closed. If they are not, then the link might need to be tweaked, or check for throttle...

    Thermoquad questions

    Enlarging the transfer slots should not be done, and likely would worsen the situation and cause erratic operation. Some notes on drilling follow. Ensuring that the throttle plates completely shut with the throttle closed ensure proper alignment. At curb idle, they are not fully closed, so a...

    My attempt at tuning a thermoquad.

    Regarding your list of Thermo-Quads as rebuild candidates, following is a listing of preference from most to least. The listing is based on the different models' attributes, but order could be affected by condition, and it sounds like some of yours might need to change order positions. Also...

    Hardware for securing fuse box to firewall for 70 Challenger

    A Palnut style stamped steel nut threads onto the screws to secure the bulkhead connector. It's a cramped space to get a good shot, but the following picture shows the nuts on my 70 Challenger: These have a 7/16" hex size.

    Grounding ignition.

    This approach will not work with MSD ignition because it connects to and fires the coil differently. However, MSD describes a method to wire a theft deterrent switch with their ignition. I don't use MSD, and I don't know if it applies to all MSD ignition systems, but from two of their product...

    Grounding ignition.

    With a stock Chrysler points or 70s-80s style electronic ignition, ground the negative (-) side of the coil. When the switch is activated and the coil becomes grounded, the car will crank with the starter but the coil will not fire. Even if the would-be thief tries to hot wire the ignition by...

    Thermoquad questions

    Although it sounds like you may already have the float setting sorted out, following is a better image of the float specification of the aftermarket brass float from a manufacturer, and some better images comparing floats, plus images of a mock measurement of the aftermarket float height setting.

    Spring loaded hood wedges

    The same wedge was used on all E-bodies and all hoods, steel and fiberglass. They were also the same on C-bodies in 1970, and started on the B-bodies as well in 1971 when the fender attachment changed from the earlier vertical mount to the horizontal mount style as used on the E-bodies. The...

    Thermoquad questions

    It sounds like you have a plan. Having the before video and the after video is good. Narrow down any intended changes that might have occurred in between, and if none that has an effect on this, look for the unintended change(s). It may just be deterioration due to debris or float height shift...

    Thermoquad questions

    That is too much fuel flowing at the nozzle at idle. There are a few possible culprits. Most likely, the primary throttle plates are open too far. If you have set the idle high to compensate for another issue such as late timing, rough idle due to a radical camshaft,or other idle roughness...

    oil filter leaking

    It's likely available at several sources for the parts, but one good place for the plate, fitting, and gasket is Mancini Racing: Mancini Racing #2402105 Oil Filter Adapter Kit This fits the 318 and other LA small blocks, but not the later Magnum engines. A standard pipe nipple will not push...

    Thermoquad questions

    The 9096S Thermo-Quad could be a reasonable parts source for many of the parts on a 6166S or 6321S Thermo-Quad carburetor. The 9096S is one of a few 9XXX numbered carburetors, along with numbers 9014S, 9015S, 9022S, 9023S, 9036S, which retained the 6XXX numbered carburetors' style main body...

    Bumper bolts

    The bumper bolt threads for the face bar on a 1970 Barracuda, and most other domestic Chrysler product cars from the 60s-80s, is 3/8" x 16. Dodge trucks can have 7/16" x 14 thread size and the head of the bolt is physically bigger. The following image shows a comparison of the 3/8" x 16 and...
