    Found my dads original 1971 duster!

    You already had much skills and experience building. I just had some insight with the fuel and timing. Lots of guys here who could help with getting it fired up with a new carb and distributor. Tuning will come later. @dads71 Check the Shop Manual for which way the clutch should face when...

    Found my dads original 1971 duster!

    There are others here who have a lot more experience than me. I have an area or two of knowledge and a bunch of learning the hard way. H'm. OK. If the carb hasn't been taken out of the box, then this will be a bit different story. How about the distributor and ECU? Did they come with...

    Found my dads original 1971 duster!

    Further comments in getting ready to tune and drive. Proform "Mopar authorized" Ignition kit. Not much info posted about the internals of these. So my advice is this. If its running OK, then the first opportunity measure the timing versus rpm from idle on up through 2000 rpm. Then if your...

    Found my dads original 1971 duster!

    There also should be no play in the clutch unit. Don't know how I forgot about that since I've been bit for ignoring that one. ---------------- Getting ready for driving and tuning, lets look at the dyno sheet. To me this looks like a pull for break in and check for problems. A tuning effort...

    Found my dads original 1971 duster!

    If its not leaking and there is resistance when when you turn the portion that holds the fan while holding the attaching flange. Some clutches had a thermal control on the front - that one probably does not. best part is that it will fit and be spaced properly without spending a bunch of time...

    Stop in for a cup of coffee

    IIRC There's a more detailed breakdown they did about the cost of the crude - how much it costs to get out of the ground, then how much to ship it, etc. Some states regulate the retailers to try to stop price gouging. IIRC NJ somehow doesn't allow big jumps in prices.

    Stop in for a cup of coffee

    A lot of places have additional restrictions on RVP. https://www.gasbuddy.com/go/summer-blend-and-winter-blend-gasoline At least one state has a drivability requirement. Its one of the midwest states IIRC but I forget the details.

    Stop in for a cup of coffee

    they're allowed get to cut it with more benzene tolulene and cheaper stuff to improve low temperature starting. \ Unfortunately we get some hot days here before switchover. Then I can smell the fuel and the car doesn't like it much either

    Stop in for a cup of coffee

    I paid more than that in the wrong location. :( But I wanted the tank full before heading home. So it goes. No idea why its going up now. The refineries don't have to start sendin summer fuel until May 1.

    My 273 turned out to be a 318...what did I buy?

    Pushing more than sucking is usually easier on pumps. On the other hand relocating electric back there is a project. Looks like the connecting and right side parking brake cables missing Good news - steel wasn't cut. If it was me, I'ld look up the specifications on the pump for 1) fuel...

    Small bolt pattern American torque thrust T70R rims

    I would have to dig through my notes. Of the top of my head, depending on wheel offset, the front end height and t-bar size, 225/60-14 may be OK, and 225/70 will occasionally contact at the front fenders - turning under compression. Also check rim width against BFG's recommended widths for...

    Vacuum Secondary Conversion

    I don't see any substantial contradiction between what is posted here and the snip you posted. Don't get hung up with the casting material. While the change in material does effect rates of heat transfer, and the change in dimensions for a given change in temperature, they are also a different...

    Formed, Machined, and Assembled in the USA !!!

    Just got these, but I don't know if they are really new, or just new old stock. Wilde brake spring tools - made in the USA. Save me the trouble of fixing the "pro" tool that came apart last week. I've bought brand new high quality Stortz paint scrapers made in...

    Vacuum Secondary Conversion

    Whoa. So you're still putting things together. OK. Put whatever intake on it you think will make you happy. Seriously. If it fits, has the ports you want, go for it. Street contender/dominator single plane if you want short, or RPM for taller (although a drop base cleaner may be needed and...

    Stop in for a cup of coffee

    Not much of a story. That's the size the fits the anchor pins and and so I was using it, until it spun. I'd be there now but told the neighbors Id help be the 'new' person with their dog trainer to get him used to people. After lunch took a call from a blacksmith who can make some htings for...

    UPS delivered some stuff today including Wilde brake spring tools - made in the USA. Save me the trouble of fixing the "pro" tool that came apart last week. and a new wrench roll to replace th ebadly decayed one that lives in the 'ammo box'

    Stop in for a cup of coffee

    Read the tips on using the windage screen. Basically its best to open them up a bit - add another pair or two of louvers. Let us know how the intake valley splash pan fits. The one in my current 340 took some fitting but I cant recall if its a Milidon or Moroso

    67 68 backup light actuator pin. Not mine.

    Dang that's expensive. What happened to your project? Was the issue too expensive to get it made out of a material that be strong enough?

    Electronic ignition upgrade.

    These has been answered, and you agreed. So now why are you asking again? All I can guess is you don't understand how the the different advances work and what you can and can't do with them. Since you want to buy an answer, then either buy the FBO system and do whatever Don says, or buy...

    Lean idle. Rich cruise.

    PS. Even when cruising, when there is a slight downhill and we lighten up on the throttle, a high vacuum is created under the mostly closed throttles and guess what happens. There's less air mass coming through and more vacuum at the idle port and transition slot so the 'idle circuit' starts...

    Lean idle. Rich cruise.

    Changing the idle mix screws changes the cruise AFR means the speed your are calling cruise is still mostly on the 'idle circuit'. It should really be called low speed or low throttle circuit, and in fact that's the term Chrysler often used. Only reason to avoid the ethanol is if you're not...

    Electronic ignition upgrade.

    This is what it boils down to, doesn't it. If a campfire is built properly I can light it with flint and steel. Using one of those extended butane lighters won't hurt but unless there are some adjustments to the build, its not going to help get the big logs burning quicker, and the end result...

    Stop in for a cup of coffee

    Nice! I'm off to play some v-ball. I was able to put together a circuit schematic of what your 64 probably started with using some 63 and 65 info. It probably would be easiest to stop by and see what you have in hand. Then figure out how to blend the old with the new in terms actually making...

    Headlight Relay Kits

    Only if there is a problem (resistance) with the power feed from the alternator to the main splice. A relay is an electrically powered switch. Installing a headlight relay uses the original headlight circuits (hi & low) to connect the headlights more directly to the power supply. A circuit...

    Short circuit 63 Dodge Dart

    In the shop manual is a wiring diagram. The spark indicates electrons are moving, since it sparked and melted the fuse you tried between the bulkhead connections and the feed wire, the short is downstream from that. This assumes everything was turned off. The battery power is always...

    Short circuit 63 Dodge Dart

    Yes. It is the battery feed to the main circuits. Removing fuses could help narrow it down but since all of the fuses are 20 amps or less, they would have blown. It seems the situation is thus. There is a short in one of the power feeds or main circuits. It drained the battery but did not...

    My 273 turned out to be a 318...what did I buy?

    I was afraid it might be hose for fuel. I was hoping the fuel filter weas getting fed from the mechanical pump that was hidden in the shadow., Only reason to run an electric fuel pump would be if the cam is lacking the eccentric. But that long hose suggests the steel line has been cut short...
