Good evening, I have a 1973 340 dart sport that I’ve owned since 1975. Im pretty sure that I have the original block and crank. The numbers on the left side of the block are 2780930-340-5. I understood that mopar used to stamp the vehicles last 6 of the vin on the block as well however they are...

Good morning. I’m trying to find a source replacement bolts for my motor mount Brackets. The bolts are 7/16-20 with a 1/4“ shank, and are 1.5” nominally. They are grade 5 and the ones I have have a “D” on the head. I’m having no luck duplicating this bolt through Dorman. Otherwise I’ll cut...

Good morning. Would anyone have a reference or a source for header gaskets for old cast iron W2 heads? I would like to try to keep the heads because they still work. However finding header gaskets is difficult. They are slightly rounder than the race head W2 gaskets on the Hughes and Mancini...

Does anyone have a simple method of removing this spring. I’m hesitant to pry it off due to its stored energy. Pry bar? Also, getting the new lower tension springs on looks interesting!

Any ideas about mounting the coil on a 340 as far as location? Also mounting brackets? What I have needs placing. Also, vertical mounting or horizontal? thanks

I have 6 old 360 heads I’ve inherited over the last 2 decades. 4 of them have hardened seats. Are they worth anything more than scrap value? Even my W2s are vastly outdated today!

Has anyone had any experience with the melling MLP-201 engine priming system. Specifically on the 340/360 LA engine.

Any opinions as to wether to use silicon sealer on the water pump gasket or torque to 30 psi with no sealer?

I noticed when I removed my MSD ignition that there is a build up of corrosion on the reluctor. The car sat for almost 10 years, and while compression is good and it runs well at about 15 advance, I’m wondering if anybody has seen or experienced this and if so, how to clean it without taking the...

Does anyone have a preference for engine stands for an LA engine?

Has anyone had experience with, or any knowledge about the Passion performance A-855 5-speed?

I have a question for the highly knowledgeable FABO folks. After installing a PCV valve on my car most of the oil leaks disappeared. However when I replaced the power steering gear with a manual gear the car sat with the front jacked up for a month. I also used a floor jack and 2x4 to raise...

Happy Friday, Good morning. Would anyone know what the correct Torque is for the exhaust to cylinder head bolts with W2 heads. The 73 Chrysler manual calls for 20ft/lbs on the stock studs but that number is for the stock head. Any favorite W2 header gaskets? thanks

I am down to the final step in the process of installing my Firm Feel manual steering gear. I have the adapter which goes on the gearbox, and the “grease pot” Steering Link, which attaches to the column. I’m thinking of installing the adapter first on the Gearbox, and then installing the pot on...

I’m sure this has been covered before. I’m in the process of replacing my old power steering gear with a Firm Feel manual gearbox on my 73 340 Dart. The steering coupler was in rough shape and after driving the roll pin out and moving the steering column aft the coupler is separated from the...

My 73 340 Dart Sport acquired an 8 3/4 rear end sometime prior to 1976. My guess it was for the anson sprint wheels it still has. My question is whether there is a recommended torque value for these. Also, I’m guessing that there are aftermarket as I can’t find any info on them in the 1973...

I have a coolant reserve system on my car. (73 Dart 340) I would like to get a coolant reserve system radiator cap. Does anyone have a source and/or a part number? Thx

Good evening folks, can anyone possibly ID these old aftermarket valve covers? I got them for Christmas in about 1980 and am wondering if I can find replacement breathers for them or if I need new ones.

Good evening folks. I am baffled and am hoping someone can point the solution I’m missing out. I have an older Edelbrock PVC breather port that is supposed to connect via a hose to the air cleaner #1205 fitting that mounts to my Edelbrock air cleaner. However if you look casually (or closely)...

I have a 340 with a flat tappet cam. I used to use Rotella with the Hughes Engines zinc additive which is discontinued. Lucas Hot Rod oil is difficult to find out west which limits my options. Any opinions on Valvoline VR-1 high zinc oil?

Hello Mopar experts, I’m reinstalling a Classic Industries fuel sending unit with a 3/8 fuel line and a either 5/16” or 1/4” return line. I am running a carb and do not need the return line and therefore I would like to plug it. (See attached picture) I used a rubber vacuum plug as a temporary...

After timing and tuning my dart I decided to drive to the gas station to fill the tank. I had replaced the sending unit because the other one wouldn’t work. Well the fuel gauge works! However after pumping about 8 gallons in fuel started pouring out of the tank. Upon getting the car home I set...

Has anyone had any luck restoring the door latch mechanism! Mine sticks constantly on the drivers side. (Pax side works beautifully). I’ve been considering removing it and thoroughly cleaning an lubing it. However I’m not sure if those just wear out or are restorable.

I can’t believe I cannot find the recommended tire pressure for my car. The sticker is history and google no longer knows. I have T/As on it. (I vaguely recall 24/34psi but my memory stinks) Thanks Mark

Does anyone know the part number for the correct throttle cable for a 1973 340 Dart. Thanks

Good morning. The drivers window on my 1973 340 dart sport has rolled over and died. I found a junkyard drivers door regulator which didn’t really solve the problem. The window does the “end drop thing” when unrolled. I’m thinking tracks may be the answer. Any ideas?

After testing my tank sending unit I reinstalled it in my brand new fuel tank (Dart/Duster). Now the fuel gauge goes to a little over 1/2 when full. Anyone have advice as to how much bend the arm needs, and/or a foolproof way to determine the bend rather than removing the unit 3 or 4 time in...

I would like to get rid of the power steering in my 73 Dart 340 Sport. In addition to taking up cubic acres of space, it is well worn. Any suggestions? Thanx!!!

I have a question regarding pushrod length. I am converting my 73 Dart over to manual brakes and I just purchased an adjustable pushrod from Mancini. It looks very much like it will fit, however, once installed it will not be possible to adjust it! Is there a Length that I need to adjust it...

I have decided to convert my 1973 Dart 340 Sport over to manual brakes from power. I ordered a Fenco NM1627 master cylinder for a manual brake system, and an adjustable master cylinder push-rod package from Mancini. After removing the existing master cylinder and the power-brake diaphragm I...
