Hi,
Guess I should have been clearer about how awesome RedHeartBeat's recipe is. Still looking for more details around the PCMs from these Gen IV units.....or maybe I need to find a "harness fairy" like Red does...lol

From other webs, I believe I want a L96 with iron block, VVT, 9.6 CR for regular fuel, or E85 and hopefully the fuel management scheme that drops half the cylinders during low load. This should give me reliability, gas mileage and sufficient power to tow an RV trailer. I have yet to secure the engine and trans (6 speed auto), but am trying to confirm what I am looking for and in what, and how many challenges lie ahead.

Any comments from experience on the Gen IV's, particularly the L96 2wd?
-cooling?
-output shaft configuration?
-the 6spd auto is supposed to have its own PCM

-looking more like I keep the 98 PCM for the ABS, what about speedo and cruise?
-any other functions to keep routing through the 98 PCM?

Thanx
