I was driving my 72 340 RR today and all of a sudden I could smell antifreeze. I saw my temp gauge was starting to rise -- it never runs anywhere near hot -- so I pulled over, stopped the car and saw steam coming from under the hood. The upper radiator hose had blown off the thermostat housing...

Hello, before I yank my alternator and take it to some box auto parts store to be tested, here is the scenario
My battery is only charging at 12.7 when running at increased RPM. The battery is good and will hold a charge. I am getting "same as battery" voltage at the alternator stud (high 12s)...
1972 AC Heater Box. Nice, clean condition. Came off a 1972 Satellite Sebring. I believe it will also fit a 1971. I won't ship but I will drive a little for a semi-local pickup. Located in Western PA. $110 or best offer.
So, I started up the 340 today and got a horrible squealing sound from the front of the motor. Sounded like bad/loose belts on steroids or the water pump was about to explode. It went away in about 10-15 seconds before I could pinpoint it. I drove around and got the same squealing -- but not...
So, I've been chasing my 14.95 overcharging battery on my 72 RR. Here are my voltage drops testing from battery positive
Red wire connector at Molex (engine side, closer to bulkhead) .16
Blue wire at Molex (engine side) .21
Ignition switch (probing blue and red wires on switch side of Molex) .12...
I am running a couple of glass fuse taps to power my aftermarket gauge/tach, and I want to make sure I haven't bypassed the fuses. Which side of the fuse should the taps go to make sure I don't have an unprotected circuit? (Fuse box is internet photo, but same one I have). Thanks
I have been chasing an overcharge on my 72 340 RR for a while. Got lots of help from you guys but I'm now officially stumped.
I was charging at 15.5 at idle and had 1.50 voltage drop from battery positive to blue alternator wire. I got it down to 14.95 and 0.9 drop after cleaning and going...
I have been chasing this overcharge for a while, and you guys have helped keep me pointed in right direction. Thank you. But I'm still too high, and electronics is definitely my weak link so please bear with me. 72 340 RR
I'm charging at about 15.25V. I get 1.5 voltage drop from battery + to...
I'm not sure about this, but how much wiggle is tolerable when you jack up front end, grab a tire at 3 o'clock and 9 o'clock and shake? I know newer front-wheel drive cars shouldn't budge. With these 50-year old cars is any movement bad or is a little movement OK?
Car is a 72 RR. Tires wear...
My battery is charging at 15.3 to 15.6 depending on rpms. I am a newbie to electronics and some of you guys are brilliant. I need help. I did research on site and ran some tests. I unhooked the field wires at the alternator and battery did not charge (I believe that means alternator is good). I...
Hello all. I am adjusting my kickdown band and rear band on my small block 727. This is the first time I've ever done this. Tranny is dated coded 1972. Tranny operates nicely (and fluid looked perfect) except right now I don't believe I have any kickdown at all (and yes my kickdown lever is...
What is going on? I wanted to fine-tune my timing on my 340. It was originally at 17 initial, 35 total (don't run vacuum advance). I looked for highest vacuum and idle. When I was done, it was right back at 17/35. This is where it gets strange. All of a sudden, I had hot start issues (never...
I have a fuel return line in my 72 RR that I don't use. I've never used it. It runs up along inner passenger fender in engine bay near firewall. Charcoal canister is long gone. I've just left it open (uncapped) and unused for years. Should I use it? Is it needed? If so, how do I hook it up? (As...
Is the float spring supposed to apply pressure to the float up or down? I have a Holley 4150 DP with center hung float. I thought spring was supposed to apply some pressure up, to keep needle closed during bumps or turns, etc. Mine gives barely any tension but if anything it's definitely down...
I'm having some carb issues on my 340 with an AED Holley 750 DP. Not sure if I found a problem. Is the arm on the primary accelerator pump supposed to sit directly on the cam? I have a gap and the cam doesn't actuate the pump until nearly full throttle. Secondary arm sits right on cam and...
When you adjust a vacuum advance canister, are you adjusting the amount of timing it puts in the engine OR the amount of vacuum needed to accuate the advance?
Four people have told me one way, three the other.
If it matters, it's a JEGS Mopar Electronic ignition distributor on a 340. Thanks
If you are changing out your fuel tank, don't order this fuel neck grommet --- OER MF-296 --- from Summit. It doesn't fit. I spent 2 hours, boiled it, used Dawn liquid, WD-40, dialectric grease. Pushed my fuel neck with all my might. The grommet is too small. In the Summit reviews about one in...
I'm putting a new fuel tank in my 72 RR. I am using my original sending unit, which I recently replaced the brass float and sock. It reads my fuel level perfectly and works really well. But while I have it out, I'd like to clean the already clean sock as much as possible. Just spray with carb...
