Full-Floaters

[Jon Mello]

While the example shown happens to be on a dragster, there is some good general information
on full floating rear ends in this old Hot Rod magazine article.

John.....Sometime in the very early '70s, John Treder had the 12 bolt fitted to his A/S.  A local shop used their "drag race bits" for the conversion.  Aside from a pain to swap crown wheel & pinion, it performed flawlessly.  Until we went from 5, to 6 litre engines (A Sedan to GT1).  At the first National at Sears Point that year, the left rear was overtaxed by the hp/torque (586/525).  The inner bearing race "became" part of the axle snout.  A quick call to the original fabricator, & he said, "Bring it down."  After one look at it, he stated, "You're still running that setup, I thought I contacted everyone & got them to upgrade to my stock car hubs & snouts!?!!?"   I still remember the smell of burned 140 wt. Valvoline!

Interesting bit of information, Steve. Thanks for posting. I know what you're saying about certain smells. I had a friend who was a mechanic and the shop where he worked had a fire and it burned to the ground. I still remember the smell on his burnt tools.

Out of interest, were full floaters used in the Trans-Am pre 1972 era?

Yes, Ford had them for sure in 69,70. Not certain in 67,68 though.

Ran across this in the Revs Digital Library.  Autodynamics Challenger in 1970.

The Javelins were using them starting in '68 and Penske started using them in '69.
