Re: LS Swap in 4x4 71 longbed

Justin,

I did an LS swap in another project.

The biggest factor for me was what I could easily find available. I ended up with a 5.3 with 4L60 and ECU pull out. I followed the instructions on lt1swap.com for the wiring harness and had no problems.

It fires up and goes straight to idle every single time.
