diff

[HK1837]

I used to run a 2.78:1 in my LX Torana behind an iron case Celica (0.85 5th) with 265/50/14 and 253/60/14 tyres. It was fine at freeway speeds and it was only a 202. It had a 30/70 cam, Yella terra head, 390 4BBL Holley and extractors. 5th gear was perfect at 100km/h. It was a bit lighter though at aroung 1350kg. When I put an A9X diff in it it was 3.08 and better, but even with the 2.78 I used to pull a ski-boat with it, and because of the Celica's tall 1st gear it'd easily pull the boat up slippery ramps.
