Fuel Return line depends on the year, check ls1tech.com for that info.

I used Hooker Block Hugger headers, and will have to have the pass side modified to fit. I had problems with the drivers side fitting, You may have to see how they fit when you put the engine in.

my 5.3 vortec swap required a return fuel line. I was unable to use the 5.3 exhaust manifolds and opted instead for some shorty headers as well.

I'm not sure on the tach but I dont imagine the oem tach will work. I believe Autometer makes a tach that is computer controlled that will work with the Vortec motor's CPU

I Need Some HELP on my 1994 YJ that im doing a swap to a 2004 chevy vortec 6.0 with a 4l80E tranny 2wd i want to know witch way would be better to go.... Should i keep the 6.0 fuel injected or switch it to carb? so i can get a 4x4 tranny and transfer case to work something like a 700r? i want the transmission to stay automatic.. Or is there a way to keep the 2wd tranny switch it to 4x4 and get a transfer case to match up and will it be a manuel transfer case or a push button one? if it is a push button one will i need any new wire because my truck did not have 4x4 ???

If someone could please help me that would be great
Thanks
