I posted a similar post in the suspension forum and thought that maybe the race forum could give me a little more practical opinions. In pulling the old exhaust we nicked a torsion bar with the cut off wheel so we need to replace it. The car is a 74 Duster with a 318 that we are building to get...

Well, when we were taking the motor out several weeks ago we had to cut the drivers side exhaust because the manifold to exhaust bolts were frozen. Of course my nephew hit the torsion bar with the cut off wheel. (murphys law you know). I just saw the nick while he was scraping the undercarriage...

I am getting ready to go at the 302 casting heads with the old grinder after having practiced for about 8 hours on my original '74 318 heads. I keep reading about how the 302 heads have less material around the pushrod and to be very careful. The articles I have read talk about using a Helgesen...

We have been cleaning up the engine compartment getting ready to have the car painted and just removed the 34 year old wiring. Much of the tape (?) wrapping the wires and harness is deteriorating and looks bad. What is the correct material to use to re-wrap the wires so they look good and stay...

What is the maximum compression ratio that can be run with good 93 octane pump gas in an iron headed motor. I am building a 318 with 302 casting heads and want to get the highest compression ratio possible without getting too close to the ragged edge of detonation on good pump gas. The machine...

Is this the correct way to determine how deep in the bore a piston is? This is a stock '74 318 and I was trying to get an idea just how deep they are. We are planning to use KB167 pistons in the rebuild with 302 casting heads and I am trying to get an idea of how to get to a 10 to 1 or close...

I know that repair/rebuild prices can be very location dependent but I would like some input on what you guys have paid to rebuild a 904. It ran fine when pulled yesterday but since we are going to be building up the engine and need a shift kit anyway it is a good time to beef it up. We are...

I have a set of 10" wide 15" chrome plated steel wheels on the back of my '74 Duster that we put on just to have something that looks better than the original skinny 14" wheels that came on the car. They came off craigslist so I know nothing about them. With the XHD rear springs they fit well...

Well, Our plan for the little teen has been changing a little. Our plan was a very hot little street car with mostly strip set up. As time has passed we are trying to conserve money and depending on what we find when we pull the motor we may not be doing a full rebuild with the KB 167s etc for...

Well, I just found out from the radiator shop that my original radiator out of our '74 318 A/C car is shot and would cost several hundred dollars to repair so I am looking to replace it with a reasonably priced stock style radiator. The car is an a/c car so it had the 26" heavy duty radiator. I...

We are in the process of building our 318 fun motor. The set up will be a .030 over bore with KB 167s, 302 casting heads with 1.88 1.60 valves, cleaned up and gasket matched to Hooker comp headers and an Edelbrock RPM Air Gap with a Holley Street Avenger 670. We are strongly considering the Comp...

I have two sets of these seats which I was told each came out of 1975 Darts. Can you guys please confirm what they are? I would like to sell them but I want to make sure I don't advertise them wrong. Thanks

Thanks for the fender Curtis!. Slid right on the car tonight. Enjoyed seeing your collection and meeting you! Also enjoyed the ride in the Plum Crazy Duster toy.

Hey folks, I just pulled my 8 1/4" single side 2.45 rear end out and installed a posi and 3.90s in my '74 318 Duster. When I pulled the rear end/axle etc I lost the rubber snubber that attaches to the top of the front snout of the differential and also noticed that the triangular rubber...

I have a column shift '74 Duster that we are changing to a floor shift. Is all that is needed to get rid of the shift indicator hump on the column a change of the collar? If so, what all is involved in swapping them out? thanks

I am still undecided on exactly how we are going to build our '74 Duster and am trying to get the best idea I can of options. If I keep the 318 and build it I want to run an Edelbrock RPM Air Gap manifold so I will have to port the 302 casting 318 heads I already have so there is not a big step...

Hello, I have been preparing to build my little 318 to try to get around 400hp and about half of the folks on this site keep telling me to just go for a 360 for about the same money and get more displacement. Here is my question. my car has a 904 transmission and an 8 1/4. I am having the...

I have posted a few posts about our plan to build an ~400 hp 318. KB167 pistons at .030, a fairly stout cam etc and then going with 3.91 gears linked to a 904 with an appropriate torque converter. I lucked on a set of 302 casting heads for $100 that had already been refurbished and are in...

I have a '74 318 Duster that we are working on right now. We are going to bore it .030 and use the Keith Black 167 pistons. I have a set of 302 casting swirl port heads that we will use after going with 1.88 1.60 valves. I am going to port match the heads to an RPM Air Gap and gasket match to...

Our '74 318 Duster has the 150 hp motor. The motor bacfires through the carb stumbles and stalls when you jump on the gas. I have put new plugs, fuel filter and fuel in her. I believe the timing is the culprit. Last night I checked the timing and with the distributor vacume line plugged it was...

I am going to be swapping the old 2 barrel carb and manifold out soon and need help on carb selection. Do I need an electric choke or can I get away with a manual choke? Since I am in Fl. cold starts are not usually a big problem. If I go with either what is required to hook each up? Thanks!.

We are in the process of trying to settle on our final plan for a '74 Duster that my nephew and I will be building. It will be just a fun car that will see strip duty and some cruise nights. It is a 318 car with a/c, p/s, p/b and a 904 trans. Here are the thoughts for the set up of the motor...

The little tag on the rear end of my '74 Duster says 2.45. I can't believe that is a gear they would put in a 318 automatic car. I have never even heard of that gear. Has anybody ever heard of that gear? It is an 8 1/4 with a 2852905 case if that matters..Thanks

I am trying to find a parchment interior door panel for my '74 Duster. Anyone have one they are willing to part with? thanks!

My nephew and I are building a '74 Duster with a 318. We are going to go with the KB 167 pistons and 302 casting heads to get the compression up. I have been researching intake manifolds and have always liked the RPM air gap manifold performance. I think the rpm range will match what we plan...

On our (new to us) '74 Duster we decided to change the fluid and adjust both the kick down band and the low/reverse band. The manual I got at Advance Auto said to tighten the low reverse to 41 in lbs and back off 7 turns. Yes 7. The kickdown spec was 41 in/lb and then I believe 2 or 3 turns out...

We have a '74 Duster with a 318 that we are getting ready to start building up. The car is all original so we decided to build the 318 and 904 rather than swapping them out. I have been looking for headers for this set up and it appears that most of them indicate that they can be used only on...

We have just had a chance to get under the '74 Duster 318 car we picked up and I noticed that the rear end of this car has coil springs in addition to the leaf springs. I have never seen nor heard of this. Is this some add on that a prior owner installed to try to remedy the sadly drooping rear...

Hello, New to A bodies so I have some questions on the suspension set ups you folks are running. We just bought a '74 318 Duster with an auto and are trying to decide on the suspension set up. It will mostly be a weekend driver however it will see the track fairly often. We want it to...

I have searched for a firm answer to this question and couldn't find it. What year and model vehicle bucket seats will fit in a '74 Duster. Both tracks and seats themselves please. Thanks
