Bring it over to the IRS race in SC next month if you want to run the 1320'.

Thanks for the feedback Rhino. The point is that I can get the complete 3.91 diff assembly for free (in exchange for my current 3.70 diff assembly). So the swap is easy and it won't cost me anything but some Labor.

My rev limiter will stay however at 6500.

Will I notice a big difference between the 3.70 diff and the 3.91 diff?

Thanks again

I dont think youd feel much difference, and I think the 3.70 would be better for your rev range to be honest. I spin mine 7000-7200.

Weather's looking good. High around 53* and little chance of rain. Of course, in AR that can change in 5 mintues.
