Do the braces that run diagonally from the firewall to the front fender aprons really do any good on a 73 B body?

Does anyone know the center to center, aka bolt circle distance of the rag joint holes on a 73 charger, mine has been so bastardized I’m not sure what it should be. Mine is 2.400” bc and 3.250” od. Thanks for any help

My 78’ 440 block has 2 extra .250” cooling passage holes on the deck below each cylinder situated between the head bolts, none of my other blocks had these, is it one year only thing?, 440 source heads are at machine shop so I don’t know if it has corresponding holes, pics on their website don’t...

I have a 73 Charger w/ factory power brakes, single diaphragm, v-band style booster and I am looking for the seal that pushes into the front housing to seal the vacuum around the push rod and front housing. Searched on this forum and on internet with no luck. Has anyone replaced this seal...

I have a Borgeson power steering box in my 73 Charger and wonder if anyone has used a cooler on their power steering and which one they would recommend. Really didn’t want to put one on but Borgeson recommended it after I called them and told them about the lack of assist after it got warmed up...

First I must say when I look at wiring diagrams, all I see is spaghetti! Someone was kind enough to send me a color coded wiring diagram, thanks! I’m just now tackling this project and have some questions. In my mind the factory wiring diagram for 60+amp shows #18 pin shares an 8awg with a 12awg...

I’m an old guy with old thinking, bigger is better?, I upgraded my factory a/c system with, I think Vintage Air, and wanted to know if I should use the supplied condenser or a two row condenser from a 77 Cordoba that I bought many moons ago? I know heat transfer technology has come a long way...

In the original Dodge service manual, top of page 8-135 instrument panel wiring coronet, charger (rally cluster), on the amp meter there are arrows pointing to the two wires a1-12r and r6a-12bk stating “not used on 60-65 or 100 amp alternators” Anyone know why? Too many amps for the gauge maybe...

New 100 amp alternator from quality power, new voltage regulator, complete new wiring harness, the problem is that in drive, 700 rpm, the needle is showing discharge, voltage is 11.2 volts, bring up the rpm to 1000, 13.9 v and needle is in the middle but in park or neutral the rpm is 1200 rpm...

Does anyone know what the voltage at the coil should be with ignition in on position? I was thinking it should be around 9 volts, I’m getting 4.8 volts. Back story, just restored, all new wiring, ballast resistor, coil battery all of it! Starts ok but once it warms up and I put my foot into it...

Found a supposedly “industrial 440 block”, it’s a 78 and it is different, for example it has humps in the valley where the cylinders are as opposed to my other 78 block which is flat in the valley. Is there such a thing as an industrial block? It’s already been to a machine shop and checked, had...

Ok mopar peeps, I present to you my first tragedy. Bought a used 78 block, had all machine work done.I assembled with 440 source 500 stroker kit, drove about 20 miles then developed a external crack on right bank pulled engine, got a 77 block and again did all the machine work and now it...

Hey guys! Working on my 73 charger, all new engine bay and under dash wiring harnesses. I’ve been working on tuning my carb and twice I leaned in through the open driver side window to turn on the key and shocked my chin, chin was touching windshield trim. It wasn’t a shock like a spark plug...

Well, got a replacement block for the one I built and installed then found that it had a crack on the outside right bank. Got it vatted machined etc. the block is a 1977 440 block but it has a 1/2” npt oil pickup tube. My 400 and the cracked 440 had 3/8” npt, I understand why Chrysler did it, I...

Does anyone know when Chrysler started putting in rear main lip seals on 440’s?

Let’s play a game! Where does this bracket go! Not really a game,, idk where it goes and it’s been years since I removed it,,,but I blasted it and painted it so it must be important! it’s off my 73 charger and I think it goes on the front bumper somewhere

My 73 ex SE is almost done, when it is I’m selling all my leftover bits and bobs, all of it at one time, no piece meal and no shipping! I live in NE Oklahoma. Because of all these rules I’m willing to sell cheap, cheap! When my project is done I’ll post in the marketplace forum. The following is...

Just my opinion,,,,, my cup runeth over! Lots to do so i farmed out my 8-3/4 diff. Made up some dummy bearings For the pinion , thoroughly cleaned all parts and took to vendor. He said we don’t use dummy bearings to set up the diff! I, not being a diff specialist, thought ok, they know what they...

Had my 727 rebuilt and it still had a very bad leak from around the gear selector shaft or the throttle shaft. I’m assuming they replaced those seals. I did tell them that it had a heck of a leak there when I took it to them to rebuild but who knows if they listened. Anyone ever had a worn out...
