It's time for the next major project for the Tundy.
In the past that truck has gotten everything imaginable. It still lives on the 5-link coil-over high pinion Dana 44 in the front and a custom rear suspension.

Now I am targeting the engine.

Here's what I am looking at:

1. Since the 4.7 is already supercharged, perhaps a blower pulley upgrade and a Unichip (easiest)

2. Prefered: Swap in a 5.7 with 6-speed and put the blower onto that motor.

3. Possibility: Stroke the 4.7, turn up the boost and see what happens

4. Trash the whole Toyota thing and swap in a 4Bt or 6BT Cummins with a Dodge truck drivetrain.

Has anyone replaced their 4.7 with the 5.7 yet?
Anyone put an earlier TRD SC onto the 5.7? My blower looks different than the 5.7 unit, and mine is an Eaton 90, doesn't the new system use a larger Eaton blower?
