Title: Why 2 ring gears
Post by: 61K T/A on January 26, 2017, 07:43:47 AM
I removed my inspection plate and this is what I found.

My guess (and this is only a guess) is that good torque converters are not cheap so they may have had a really nice one that was to small.  So welding a larger ring for the starter was all that was needed to use it and save some money.   :dunno:  It's only needed to start the car anyway, so as long as it's welded on good and balanced, probably will not an issue.

That was some idea some one had eh? I've never seen that before, any where.  Must be old school technology!

Don't know, yet. No need to drop the trans.

What's wrong with your trans?

The trans shifts fine. While i'm replacing the 6qt. pan to a 7, I wanted to "inspect" what's behind the cover.

Don't need to drop the trans to find out. While idling at a stop, stab the throttle all the way down, observe how high the rpm needle flashes before the car starts to move. This is your convertor flash stall speed.

This motor explodes when I stab it. I almost crap my pants. I was concentrating on the road and not my gauges every time I drove it.  :takealook:

Only takes three seconds from dead stop on the street in front of your garage. No need to drive it any where but 50' forward to test the flash. If its that powerful, you'll blow the tires off an may not move forward at all, but then you'll leave a couple of really cool racing strips in the road.

Of course, you could take it to a drag strip on test and tune night where you can do this on a prepared track in front of the watchful eye of trained safety crews. Would also give you a chance to lay down e.t. and m.p.h. numbers to validate your seat of the pants feel.

Considering that it has the bigger 7/16ths bolts it has to be an aftermarket stall. Can't say I have ever seen one with a ring gear like that though. But if it works fine and your happy with it I wouldn't touch a thing. The stall test would be a good thing to try and it's fun too!
