So I got a 5.3L out of a Chevy avalanche 2005. My question is what do I need to take off the truck to make this run later befor I send it to the scrapper. Also what swap would this be L6 Ls1 so on so I know what parts to by later thanks

I would take everything under the hood as far as electrical. PS hoses, Belts, Rad Hoses, exhaust Y pipe with the 4 O2 Sensors, air intake ducts and the fuse box. Wiring to the transmission,

take everything that is connected to the motor/tranny by wires, hose, or cable....I'd scrap the donor after I was done the swap.

I moved this to the LSx section for ya. Here is my "shopping list" for when I bought my engine and trans.

Engine with everything attached (alt, Power steering pump, Water pump, AC compressor, Fan, coils, throttle body, manifolds).
Radiator and any hoses.
Any coolers that are separate from the radiator (trans, oil, power steering) including lines +hoses.
If vacuum boost brakes check valve and grommet.
If it uses Hydro boost brakes(instead of vacuum), the entire hydro boost setup.
Trans with mount, mount bolts and drive shaft.
Starter with bolts.
Computer+harness+fuse box w/all battery cables.
Gas pedal+TAC+harness.
Exhaust Y pipe.
OBDII port+wiring
If vac boost check valve and gromet.

I still managed not to get the TAC(Throttle Actuator Controller)
