Posi is stronger than the open. Brace the axle tubes and you probably won't have a problem.
Not to self Don't let Jim drive car.
Well,,, when Jim Comeau and I went to the first big convention in 2004, I talked him into letting me try running his 62 Impala convertible down the track a few times.
The car had the stock posi rear end, street tires and a four speed. The engine was a 476 ci stroker.
Anyway, I managed to make about a half a dozen passes before this happened....

One axle sheared right off and the other was on the verge of letting go.
An automatic transmission is a lot easier on driveline but I'm guessing that sooner or later the stock driveline is going to be a problem for you guys.
On a happier note,,, it sounds like you guys are getting that car dialed in.
I hope you continue to make progress. I guess 12.50's will be the next goal.
Well I be that lucky that you will be in Byron Il on the 12th.And Phil happened to have a spare set and Jim and Jim changed them out in the show car parking lot!!!!!!!!!!!!!!!!
So what is the life span of the axles if one was to stay with the stock rear end?
That looks painful
James... These were new Moser 17 spline axles... I did this with my baby W motor on slicks... If that thing hooks hard with a stock posi...look out!!

That's what I was thinking Grub. But then in the classes that they were running I. E. Driving for chev wouldn't they have to be factory to meet the class and their sponsors make?Steve, donors from Pontiac, Olds and maybe even a Ford.
Or a shit load of free spares.
