How would I fix the speedo in my 91z with the new 4.11's?
Thanks,
Adam

Bad news. There isn't a direct drive and driven gear setup. This means that you will have to change more than one thing to make it work. You might have to change your drive and driven and maybe tires etc. I got one set from Lingenfelter but that was a custom set according to them and cost around $120 if memory serves me.

Why do you want 4.11 anyway?

 

According to his sig, he's gonna drop an LS1 and six speed in it?
I'd take it to a speedo shop, and let them play with gear combos. They should get it pretty close for around $100.

Thanks for the help...I'm going with the 4.11's because this winter an LS1 and 6 speed will be going in the car...just planning ahead !
