I'm Going To Put A 13b In My 82
#11
thanks a bunch guys, the 13B I'm going to use is out of a 2nd gen Its a 86-88 not absolutely sure. I guess I will use my FB tranny but man I'll say it again I love how the 2nd gen tranny is geared but I don't want to have a heart attack trying to install this 13B........ Oh **** I remembered another question which header should I get a GSL-SE header or a 2nd gen header.

2) The 2nd Gen N/A Tranny isn't *that* much better.
By the way, the Best FB combo EVER for highway cruising, was the bone stock 1985 GSL-SE.
Swapping for a TII Tranny will only be a better ratio than a regular FB, but not an SE.
For THE Absolute best low RPM cruising, an Second Gen GXL tranny would probably be best, to an FB rear end..
So according to these numbers, my TII Tranny and SE rear end would give me a final drive ratio of 2.931, slightly worse than my stock configuration, but worth it for the strong tranny.
Also note that the tire size, diameter will have the same effect as changing the gears, so a rim/tire combo will yield better cruising RPM as well.
