Default 5.3l swap 1991 c1500

Hey all,

I don't post too much over here so I figured some may be interested.
This is just copied from another forum, I will update as I go.

Ok early august I started my 5.3 swap, I bought a 5.3/4l60e combo from a member here. Since then, I have pulled 4.3 and 5 speed.






Right now I'm swapping the brackets on the frame to the v8 mounts. more pics as progress is made and weather permit.

And now for something recent. Engine is about ready to fire, still need to clean up the wiring a bit.

Walbro 255lph fuel pump is installed, fuel lines hooked up, just need little stuff now like hoses and and a belt.


Still have a bunch of cleaning up to do w/ wires and such.
