HARRISON'S 5.3L LS CONVERSION PT.3

After a few final steps Harrison's 5.3 swap was finished and ready to get some miles under its belt.  Since we are using the Holley EFI system everything needed to be plumbed, fluids topped off, and a full exhaust system installed.  With all of those things finished we were ready to load the base map and get it started.  As I said before, the Holley system is amazing.  We selected a map that was within our displacement and cam profile range.  From there we specified injector size, fuel pressure, IAC type, etc.  Once everything was entered, the programming was sent to the ecu and a test fire was in order.  On the first try she fired to life and sounded great.  Now that the motor was running we put it in learn mode and connected the supplied wideband O2 sensor.  After checking for any leaks and making sure everything was operating correctly, we sent it down the road.  As of now the car has about 800 miles on it so we will get it back in and take it out of learn mode.  Here are a few final photos of the car before we gave it back to Harrison.
