I have a 750 cfm Street Demon carb on the ~450 HP 360 in my '70 Duster with a stock replacement Carter mechanical pump and stock 5/16" fuel line all the way from the tank pickup to the carb. Fuel supply seems marginal for my power level as after a second or 2 at WOT I can see my AFR slightly...

I have a 1972 D200 that I installed a Pertronix Digital HP ignition system on along with Summit billet (mag pickup) distributor. I have an issue where the voltage to the wire that tells the box to turn "on" sometimes drops below the minimum voltage during cranking. Oftentimes if I crank the...

Set of 8 forged ICON 9947 pistons for .030"-over 440 RB engine mounted with KB press-fit pins on new 440Source factory replacement (#200-1132) connecting rods. Comes with matching Hastings ductile moly ring set. Got these prepped by a reputable racing engine shop in CO for my 440 build but...

A couple years back I started building a 440 to swap into my '72 D200 pickup; at 5000'+ elevation back in Colorado the power from the mostly-stock 360 was a bit lacking. Now since moving to basically sea level I find that the 360 is more than adequate and will likely just swap in an A-518/46RH...

So it's that time of year here in Georgia where I'm sometimes using heat, A/C or having the windows open. My house has a heat pump and I noticed that when I use it in heating mode, the compressor only runs for about 5-10 seconds then kicks off and I get little to no heat from the vent registers...

My 440 build has been put on the back burner and I decided to go a different direction with it (Max Wedge-port heads) so I'm selling my Mopar Performance high-rise dual plane intake manifold. It's a direct copy of the Edelbrock Performer RPM but has "MOPAR WEDGE" cast into the front runners...

I've had a 904 in my Duster for years that's worked great. A few years ago the valve body cracked and I replaced it along with doing some zero-buck shift mods thanks to some members here (everything else seemed fine when I pulled the pan). It really firmed up the shifts especially 1st-2nd and...

Any members going to be there? I'm planning to take my Duster, it'll be the first time running it at a drag strip since I put in the current engine (~450 hp 360). The car is set up more for road racing but it hooks decently on the street with the 275mm-wide rear ultra-high-performance...

I have a pair of new-in-box BBM Stealth heads for sale. I originally bought these for a 440 I started building last year but I changed direction with the project. I did open the boxes just to look over the heads (they're in fine shape) but put them back into the original packaging. They are...

I've finished moving into my new house that has a 2-car garage but half of the garage is currently taken up by all of my larger car parts (engines, transmissions, blocks, hoist etc.) and I want to get that crap out of there so I can actually use that garage space. I'd like to put a storage shed...

I found out a couple months back that water is leaking into the trunk of my 1970 Duster. Unfortunately it must have been happening for a good few years because I had (stupidly) taped down some cheap roll-up insulation in an attempt to reduce noise probably 8-10 years ago but it didn't work...

I have a 5.9L Magnum short block in my '70 Duster with Edelbrock open-chamber heads and RPM non-Air Gap intake. I have a recurring issue where oil is leaking out from the area on the passenger-side bank where the head, block and intake mate together. I assembled the engine using the 'big bead...

I bought a Summit brand kit of Holley carb jets for the secondaries on my Street Demon because I wanted to richen it up but something seems off. I went from the stock #86 to #88 jets and my AFR is about the same or possibly even leaner. Before that I had 54x38 metering rods and #87 jets in the...

I just got back today from interviewing in-person at a company in Georgia (I currently live in Colorado) and I'll most likely take the job if the offer is what I'm looking for. However I have to figure out how to get my 3 vehicles and all my engines and parts transported out there. What do you...

The vacuum pot that actuates the air-recirculating door on my '72 Dodge truck is going out (has a hard time returning the door to closed position), anyone know where to find a replacement? Or if there is a way to "repair" it? I'm guessing the diaphragm inside has a small tear or leak of some...

I've had this truck a few years now and when I first got it I removed quite a bit of add-on wiring that previous owners had put in, I assume for powering stuff in their camper as that's what this truck spent most of its life as. One issue I still have though is if I go to crank the engine with...

I know this stuff has been covered before but the other threads I found didn't exactly answer my specific questions. I bought a 3.55:1 ring and pinion from Dr. Diff along with a clutch kit for my Dana Powr-Lok diff. My Duster has been running a 1967 741-case with sure-grip and 2.94 gears. I...

I have the original bumper jack (minus foot plate) from my 1970 Duster that I never use, it's just been sitting around since I got the car over a decade ago. Works fine as far as I can tell, ratcheting mechanism is in good shape. I'm looking to move later this year and it would be one less car...

So I've been living in Colorado the past 17 years or so and for several reasons am seriously considering relocating. I'm tired of the insane housing prices, lack of engineering industry in fields I'm interested in (power generation/energy conversion) and most of all serious lack of ethnic and...

I have a pair of factory upper control arms off a 1971 Plymouth Satellite. They're in great shape physically just need to be cleaned up a bit and the bushings and ball joints replaced. I can remove the old ones for extra cost if needed. Located in northern CO, 80538. Looking for $80 plus...

Like the title says, looking for factory-type (OE, Crane, Isky etc.) adjustable iron rocker set for a BBM. I'm building a 440 and want to go with a mild solid flat-tappet cam, I want affordable rockers that will last but nothing fancy and not aluminum.

I'm building a 440 to swap into my '72 D200 and need an oil pan AND pickup for it... let me know what ya got!

Back in May after I finished grad school I decided I was done using my '93 Jeep Cherokee as a daily driver and started looking at newer cars, particularly Acura TL/TLX. Well as some of you may know the used car market really started to go crazy over the summer and I watched the prices just...

This is somewhat related to another current thread but I'm willing to go a few different routes depending on the advice I get. I have a '72 D200 pickup currently with a 360 and 727 (2wd). I recently picked up a 440 core which I plan to rebuild and swap into the truck. I also picked up a big...

I'm looking to put a 440 into my '72 D200 and I need a rear-sump truck oil pan and pickup as the core engine came from a C-body. Send a PM with a pic or 2 and an asking price, I do have the C-body pan I'd be willing to trade but it's very dented. Peace!

I hope it's not an issue since this isn't about an A-body but this is still the best place by far to ask any Mopar-related tech questions. I have a 1972 D200 pickup with a good-running 360 but after towing my Duster to the track and back 120 miles away up and down the front range of Colorado on...

So I've had my 1972 D200 pickup for a couple years now and have been doing repairs and upgrades here and there. It has a 360 which so far I've replaced the heads with rebuilt late-70s pieces (stock heads were severely worn) and when the heads were off, the cylinders were in fantastic shape, no...

So this is completely unrelated to Mopars but my buddy is building a 2.5L GM 4-cylinder to swap in his Miata and bought these headers. He's concerned about the lack of welds on the inside of the tubes to the flange, I said it's probably not a big deal but what do you guys think? Figured I'd...

I stumbled across this video and after watching it I think this guy has come as close to identifying the issue (and fix) as anyone. He worked as a Dodge/Chrysler/Jeep tech for years so he has tons of experience with these engines. He did mention Uncle Tony's video (without any name-dropping)...

I noticed Sachs has recently come up as another option for cheap shocks besides Monroe and Gabriel. I have a set of Gabriels all around on my 70 Duster now but the fronts rode overly stiff at first then blew out within a few months. I've run Monroes before but they were overly soft and also...
