I guess the diameter of the wheel comes to play too... with my 4.36 i'm only able to do exactly 70 mph (based on my G-Tech Pro RR) at 3500 rpms but that's on a 235/40/17 size tire on a 17x9 wheel. The overall diameter of the wheel is about 24.5". My speedo is completely off and is showing that i'm doing about 85mph.

The 4.36 does liven up my stock KA... it pretty much allows me to shift sooner than with the stock 4.083. Gave me that bit of extra kick when i would exit turns last weekend's autox in el toro.

I'm not quite sure if it would work but the speed sensor gear off of an SR tranny that came with a 4.36 final gear might fix the speedo problem. I might just have to try that one first to see if it works.
