So, no disappearing tread from the rear tires yet...

You going to find some sticky tires for the cone run ?

I have about 300 miles on it so far. Hoping to get some more miles on on Sunday.
The gear ratios work well with my 3.31 rear end gears, and overdrive sure is nice on the highway.
I have a 1:00 slot on Friday to run the cones at SMN.. Looking forward to that!

OD is awesome! I'll never have another muscle car without it.

I'll be over at the QA1 Autocross at 1 p.m. to watch the trashing...I mean thrashing.

Adjusted the length of my flywheel bolts this morning and with the help of Chris P again we got everything put back together.
After some testing on jack stands it finally sits on the ground again.
I had to wait for the rain to stop but have about 20 miles on it and it works well.
70 mph= 2100rpm. You can’t even hear the motor running it is so smooth!
Mc Cleod wants 500 miles of stop and go driving on the RST clutch before running it hard so I‘m headed back out. May have to take it to work this week.

Which over drive ratio did you get, the numbers work out to a .69 OD. I thought you were getting the .80?

The Transmission I got has a .69 OD and was built for someone higher on the list who backed out. Though it is not the ratio I originally ordered it works fine.

Same old worn out radial T/A’s this year Mitch.....
