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...

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 Even my W2s are vastly outdated today!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.

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

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...

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.

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?

I have a question for the "most knowledgable folks" on-line at "For A-Bodies Only! I have a BG 650 Claw on my 73 Dart 340. The car did well on it's annual compression check, and pulls 7.5" HG with the curb idle adjusted inward to 1.5 turns and then richened to 1 5/8s (or somewhere in that...

Any good suggestions regarding affordable "under the hood" tune up tachometers?

Hello, I'm curious as to how other 340 owners accomplish compression checks on cylinders #5 and 7. I have the typical headers on my 73 Dart Sport. Needless to say the headers do a great job of making access to #5 and 7 plugs difficult. Pulling the plugs on those two cylinders is a pain in the...

Hughes Engines had a good article on oils last fall. Their recommendation for "flat-tappet" engines was Rotella T. Supposedly Shell Rotella still contains zinc, which helps reduce cam lobe wear. Any feed back or ideas; positive or negative?

After years of struggling to get plugs 5 and 7 out from behind those nasty headers, I've started to wonder if anyone has any cool tricks which might make this job a little easier? I have a ground-down Craftsman spark-plug socket, and the usual Craftsman ratchet and flex attachment. It's tight...

A few years ago, I purchased a hex shaft to prime my 340 after sitting over winter. The problem that I have run into is that after removing the distributor, I cannot get the intermediate shaft out of the engine. The intermediate shaft is tight, and resists pulling out using large needle-nose...

Does anyone have a source for the dual sender (#53030493) for both oil pressure and idiot light? For that matter, does anyone know where I can get a 20PSI switch for my light versus the standard 8PSI switch (#4169629)?

Okay, so I cant type and help my son with his homework. I meant intake manifold gasket, not head gasket! No wonder the confusion. The intake manifold gasket has developed a leak. i would like to replace it. However, after removing the bolts, the manifold is acting like it is glued on...

I am trying to remove a very stubron head gasket on my 340. I have been trying to pry it off and am getting nowhere. I have broken a screwdriver tip, and am worried about eroding metal off the head or damaging the manifold. I think that the gasket was put on with gasketcinch. Are there any...

After speaking with the Hughes Engines folks, I'm wondering if anyone has had luck installing their intake manifold gaskets dry; sans the typical RTV on the corners? I'm used to gaskacinch and the Permatex glue job, but am open to new ideas!

I have a leak on the rear portion of my engine. I put dye in the oil, and using a black light, have determined that the oil seems to be coming from the rear main. I checked with a mirror and could see no evidence of oil oozing from the oil gallery plugs or the rear cam cover(what ever you call...
