Weekend progress - 5.3 swap - pics

[Lane]

When I did my LS1 Fox Mustang I had to clearance the firewall a little with the butt end of a 2x4 - after it was painted all nice - the engine was so far back.

Nice looking install, Lane! Are you using the factory LS1 electronics on these engines, or something else?

Greg - the motor will go in - and come out with all the front accessories attached(including the AC compressor) no problem.

The wiring for the "ZO69 is super easy...It's a 5 wire hook up, and the ECM is about half the size of a VHS tape. Built into the harness are fuel pump and cooling fan relays....pretty cool.

The 5.3 can't be too much different.

Gonna be sweet !!!

On the Mustang, I used a trimmed down LS1 F-bod harness - and a tuned computer.

I'm using a 5.3 truck harness that I'm going to have a buddy go through. Trim what I don't need - and maybe extend some of it so I can hide the computer. Gonna try to make it as clean as possible.
