I'm getting ready for Moparty at Bowling Green in a couple weeks and needed to run my car to see how the new Thumper carb runs and do some tuning. The car has a Strange S-60 in it that's about ten years old. After loading the car on the trailer I go in the shop to get my jet kit and air pan and there's a puddle of gear oil where the right right rear tire sat, okay the seal is bad. I called Strange to order a couple seals only to find out they don't sell them. [censored], you build and sell rear ends but don't sell the parts to service them? Horse $hit! I sent Cass a e-mail, hopefully he can fix me up.

To add to that the over charging issue that I thought I had fixed is back. When I got home tonight I backed the trailer up to the shop to unload in the AM and noticed a wet spot, yep friggin battery acid dripping from one of the hold down bolts that come through the trunk floor. Now the battery and box have to come out and everything washed down and neutralized with baking soda...... again. I had this issue last year and Powermaster replaced my alternator at a reduced price. This never happens when driving it on the street only when its been to the strip and tonight is the first time its been to the track this year. Could the battery be bad and still start the car fine? I did a load test last year when I had the problem and it checks good. I hate to put a disconnect on the alternator but may have to. Time is not on my side to get it fixed before BG as my wife and I are going on vacation the week BG starts and will not be back til Thursday and I have to load up on Friday Am to head out. Plus, I work 12 hour shifts and have to work every day until we leave for vacation. It sure would be handy to be wealthy enough that I didn't have to work. LOL

On a positive note, the car ran good and Dom's carb was jetted pretty much spot on. Looking at the afr's I thought it may be a touch lean so I changed the secondary's to the larger jets he sent and it lost a little mph. It ran 6.31 @ 108.69 with a 1.3830 60' through the mufflers before the jet change. After the jet change it ran 6.35 @ 108.29 with a 1.3803 60' through the mufflers. I removed the exhaust and it ran 6.28 @ 109.21 with a 1.3839 60'. The last pass I tried the trans brake, two step set at 4200, instant smoke. The last time out the car was making a hard move to the left so I readjusted the Cal-Tracs, tonight it went straight as a string.

Sorry for the rant but I'm being forced to work a bunch of overtime, time that I need to be home to get my junk fixed and right now time isn't on my side. I keep remind myself it could always be worse.

My S60 leaked from the get go . Fitted a factory dana axle seal no leak , the sealed bearing(green) isnt really sealed i guess . Not the only one ive done this too , not all Strange . Seems the bearing is at fault .

I bought a front disc brake kit from Strange two months ago, as usual I double check so I order right parts. This time it was wrong bearing in the kit and missing parts, pointed out it was bearing for -73 and up and not for a -70 I have..... New parts arrive, and now is the kit complete, fine! Guess what..... Yes, new bearings is same as first time whistling

I had Mopar muscle cars for 35 year now and still love this hobby. BUT last 15 year has been a mess with poorly constructed parts, mismatched parts and complete junk and this is from well known companies down

My Dana 60 was leaking like a son of a gun, especially if it was leaning. I gave the rearend a good look and it didn’t have a vent. I bought one from Summit and mounted high on the tube and it hasn’t leaked a drop in six years.


1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

Livin and lovin life one day at a time

Mine has a vent, when I get it on the lift that's the first thing I'll check. The last time I drove it was a couple weeks ago tuning the cruise on the carb. It was hot and I'm hoping the vent is plugged and it just pushed out the oil when it got hot and pressured up.

I feel your pain. The last 4 years have been crazy for me. No time off, vacations or anything. Too many hours to count. I’m wore out and exhausted. Just want to get my car back on the road and just don’t have time. So I’m still buying up parts and patiently waiting on the day I get laid off.

Over charging is usually a sign of a bad ground somewhere - is the engine solidly grounded? is the alternator case getting a good ground connection? A bad ground will cause low voltage across the alternator - and the regulator will go wide open trying to compensate - I usually run an isolated ground from the battery up to the front and ground the alternator to it and then a braided copper ground from the engine block to the frame

The leaking rear-end is usually solved by installing a standard dana axle seal in the tube - even with the green bearings its cheap insurance - also don't overfill the rear-end as it will push the oil out the axle tubes past the seals every time!

The alternator is a one wire GM CS121 from Powermaster with the battery in the trunk. I'm using a chassis ground from the battery to one of the roll bar pads in the trunk. Under the hood the ground is on the k member to the block, the alternator has a ground to the cylinder head. Last year when I had this issue I measured the voltage at the alternator and the battery at idle and 3500 or so. The tech at Powermaster told me the alternator was working perfect and that I had a battery issue. After load testing the battery I called back and was told to send the alternator back for testing. They found something wrong inside and sold me a new alternator at a discount. It only occurs at the race track, I turn it 7200 or so. The pulley ratio is good, in fact I'm only running a 5" crank pulley. I may put a new battery on it just to see, at this point it's about all I have time for.

What does your voltmeter read at 7200? The RPM range that it sees at the track is closer to 7200 than 3500 I suspect. More sustained RPM could equal more charging voltage if their regulation hardware isn't up to the task. It doesn't take much over 14.5 V to boil a battery if there isn't any other loads to speak of on the system.

I was told to run only one quart of gear lube in both Dana 60 and 8 3/4 for drag racing by Tom Hoover at one of the drag seminars back in the old days before Mopar went B.K. the first time, it works well up
I think it says to do that also in some of the old Mopar drag racing bibles scope

I was going to say overfilled. They just don't need to be filled to the plug. If anything is going to leak, the green bearing will.


If the results don't match the theory, change the theory.

Grounds should all be connected to the battery with copper conductors.

It was filled to the bottom of the plug, you’d think it would’ve leaked some in the ten years prior to now if that was the case. shruggy

I may put the mopar alternator back on, never had this issue with it. Just the normal dim lights at idle.
