RE: [Chevelle-list] rear axle ratio??

Never said to lay UNDER the car and watch the driveshaft, Wayne.  It's easy enough to look underneath the car while knealing BESIDE the car and see the point of the wire tie to see when it gets close to or just after the third revolution as the tire makes a full revolution.  After all, you have to have the 2nd person stop you at one tire revolution.  Unless you have a 4+ gear set, the tie is going to be real close to where it started (pointing straight down) to determine its final position at one full tire turn and will indicate a high 2+ or very low 3+ gear ratio.    It's not like the fella that wanted to take the hood off his car and have his buddy ride in the engine bay and look down the carb to see if the vacuum secondaries opened at full throttle. :*) Dale McIntosh TC Gold #92/ACES #1709 67SS/67 Elky Dale’s Place – My 67 SS and 67 El Camino ChevelleStuff – Decoding info on 64-72 Chevelles Team 67 – 1967 Chevelle/El Camino Specific Midwest Chevelles – Midwest Chevelle Show Information -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wayne Sent: Wednesday, July 23, 2003 5:55 AM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-list] rear axle ratio?? Thanks for a real  FOOL proof method. Dale ... Not being a Lawyer. I think I would include a disclaimer in this technique. A guy gets  a Bazillions Dollars because his Motor Home RV  called Cruise control " Auto Pilot" and he left the controls to get a cup of Java !   Just the thought of one person driving and another laying on the ground watching the drive shaft could = disaster One positive note... they would be candidate for the Chevelle Darwin Award    :)   Wayne ACES # 1556 TC # 186 ----- Original Message ----- From: Dale McIntosh To: [EMAIL PROTECTED] Sent: Tuesday, July 22, 2003 9:43 PM Subject: RE: [Chevelle-list] rear axle ratio?? Here's another method you can use and takes two people.  Get a large wire tie and snug it around the driveshaft with what's left pointing down (6:00 position) as a reference, i.e., don't snip off the end.  Make a chalk mark on the tire at its lowest point on the ground.  Carefully push or drive car one full tire revolution while 2nd person watches the wire tie on the driveshaft and counts the full revs.  When the tire has made one full turn, look at the wire tie.  How many full turns did it make and where it is now in relation to pointing straight down.  Did it make just over 3 turns - could be 3.07 or 3.08; 3 1/4 turns - 3.23, etc. That will get you close to the final ratio with whatever wheels/tires are on the car now.
