which LT230 ratio transfer case for a LS swap?

fellas, I am in the process of building my truck for the GM LS series motor . I am going to use a LT230 case and need to know which one i should go with . I plan on running a tire around 32-33 inches tall. should i go with the 1.2 or the 1.4?



thanks,

Justin

Stock tires are 31.5". The '97 came with the 1.2 LT230Q, you want the 'Q' regardless.
Are you going to drive on the highway much, long trips, or are you going to 'trailer' your rig to events?

With a GM LS series motor V8, I would do a 1.2 without a doubt.

Will there be CARB issues with doing this engine swap into an '87 ?

Agreed 1.2 is fine with the Rover V8. There are ratios to about 1.0 from Ashcroft.

So will this T-case (1.003) bolt right onto a Zf4HP22 (standard in the '97 D90 & D1) ??

As far as I know it will. There are adapters, IIRC, for the LT230 to the TF727. I think the only real difference is that it has the higher high range ratio.

The ls has more than enough power for pretty much any ratio
