I did the initial build on this car in Dec 2010, and in the last couple weeks overhauled the car installing new parts and modifying others to make the build more refined.

This is what the car currently looks like, has come a long ways in 9 years since I bought it.

With the recent overhaul I swapped in the Holley 302-1 Oil Pan for proper ground clearance. It is flush with the Engine Cradle.
I used to have the GM Muscle Car Oil Pan, also called the H3 Pan.

Pics below comparing the two..

I freshened up the T56, and installed the Monster Stage 3 Clutch to get a little more bite over the LS7 Clutch I had

Once that was done, the package was bolted together and ready for install. The Holley Pan is about 1/4" lower than the T56 Bellhousing

Mounts are the stock Gbody SBC Clamshells bolted onto LS NON SETBACK Plates and on the factory cradle pads

Fuel System has been the same for 9 years without issue. GM EFI Gbody Gas Tank, GM Gbody EFI Sending Unit modified to work with the LS Setup, Walbro 255 Pump.

Gas Tank I used

First thing I did was take the Sending Unit and adapted it for the LS Return setup. The way it was setup from the factory is the 1/4" was the return, and the 5/16" was the EVAP Vent. I turned the 1/4" into the vent, and the 5/16" into the return for the LS fuel system.
I modified the Sending Unit by cutting off the baffle on the end of the 5/16" line and opened up the end of it. This picture here is BEFORE I drilled out that little pin hole there. This little hole on the 5/16" line NEEDS TO BE DRILLED OUT.

Once that is done, then cut a vent in the 1/4 metal line to vent the tank. This helps, it still gets a little splash back on fill up but that is by the design of the whole system. Cutting this slit on the 1/4" now turns that into the vent for the gas tank.

Here is the finished setup with a Walbro 255 GSS 342 Pump installed. The threaded flange was also cut off of the 3/8" line on the sending unit

Install into the EFI Gas Tank and run the proper EFI Rubber Lines

Thanks. I had another thread but since I did the over haul and newer parts fit, I figured I would make this to help people see what works and if they have reading comprehension with skill they can build a car up

You would be surprised. With all the swap parts and build threads out there and on here, people are still clueless. An LS should be able to throw itself into anything at this point.

I'm not surprised really... the facebook groups I admin we see it all the time. People are lazy. I even took the time to make a section of this mentioning what parts I used and I bet someone still will ask.
