Truth or Fiction.

[DAYLEY/CHALLENGER]

A crazy idea came to me today and I thought this would be a good thread to get to the truth behind old tales.
To start off this thread, I am going to relate something I heard years ago and don't know why I thought of it today, but here goes. 

We had a 62 Chevy, 327, power glide.....battery was acting up. Since I was born in 51, this just may be a tale, may not be.  I remember being told that if you ,with the automatic, were to get the car pushed up to a speed of at least 35mph, then the engine could be started. I guess from the pressure produced in the transmission would turn the engine over. 

Ok, real information or a Tale?

[CudaMoparRay]

True, Real information.
But the danger was the speed at which both cars were traveling made it easy to bump into each other and possibly cause damage unlike a manual stick that could be pushed by even one strong guy to start it.

[DAYLEY/CHALLENGER]

Thank you for verification.....     ...and I do not know why I thought of it but.........

Now do any of you guys out there have other bits of strange tales or ideas that need to be settled?         Post up.  Thanks David.

Another experience.............
Attended Nashville Auto Diesel School in the early 70's........in one class with real engines, the instructor would to something to the engine so it would not run.  We had to figure it out..........

It was an old 6 cylinder and we looked all over, changed a couple of things and tried to start, she started and ran well.  The instructor came over and looked very puzzled.........pulled the coil wire out of his pocket........and asked us if we had changed that.....no we hadn't ...........come to find out, the black  "wire" with the ends on it was a black vacuum  tube.  No wire inside.  But being used around the shop so much, it had become so contaminated with oil and such......it carried voltage..

This is a true tale............just like in the diesel section.........don't put your clipboard up to the air intake............but we did feed one a little paper!!!

  OK here is one that I read years ago in a magazine, it's about mystery engines that never made it to production. The engine in question is the quad cam hemi, supposedly two were built for testing in response to Fords Semi Hemi 429 that Ford was planning on campaigning in NASCAR. They got to the point of mounting the quad cam hemi on the dyno for testing before the plug was pulled on the program because NASCAR banned the 426 Hemi from competition and set restrictions on all engines. Before this happened the Manufacturers were in a horsepower war much like today but without the computer programing. This story came about because a demolishing company was going to tear down a warehouse in Michigan I believe and when they went in to check the building before demolition they found one of the engines in a corner under a cover, turns out that Special projects division of Chrysler would store all sorts of things in there. I don't know what ever happened to the engine but it's probably out there somewhere.....

A two stroke joke Detroit Diesel will run backwards. My old boss had this happen with a 6V92TA on his yacht. Here I am pulling them out and we installed John Deeres instead.

I don't doubt the story one bit. Ford had a single overhead cam 427 that NASCAR banned from use.

On the first scenario, On early automatics (for the 727 65 was the last year) they had two pumps, one driven by the torque convertor & one by the output shaft... If the trans has a rear pump pushing the car will create hydraulic pressure & eventually will build enough to couple the torque convertor & engage a clutch & band.... The pump isn't really designed to start the car, it's small & really was intended to lube the transmission in the event the car is towed.....   After 65 model year if a 727 equipped car is flat towed the driveshaft should be removed...

Yep, at the NADC, we did have a diesel that we could catch just right and it would run backwards.........Thanks for that reminder...

Some interesting info so far............

This is my understanding as well, it only works with early transmissions such as the early TF that had an oil pump driven from the trans output.

Great topic Dayley/Challenger,

Here is one that I think has varying degrees of accuracy;

Does a battery sitting on a concrete floor go flat faster than one that is sitting on say a timbre pallet.

I have often wondered if double clutching is a good idea,  and if so, why?

[redgum78]

The closer the gear speeds are the less work the sincromesh has to do to equalize so in theory double clutching should increase the sincro life. In practice though it probably does not make a huge difference unless you are super aggressive with your gear changes.

I always heard that too but never wanted to test the theory!!!

I don't even double clutch a truck. Why wear out the throw out bearing and clutch.
