$2000 will take the whole truck. Was a great runner until it met a fence post. Needs LR door and lower cab work, drivers sdie window, rear axle, and front bumper for sure. Other stuff is cosmetic but would make great plow truck or off road toy.

If not sold by next friday will be selling parts off it

Email for more info

I'm nit picking, but technically it's not an LS motor. The LS engine code was for passengers car engines with the only truck applications being the 6.0l LS2 in the Trailblazer SS and Chevy SSR .

The 5.3 is either an LM7 if it has an iron block, or an LM4 if aluminum block.

It is a Gen3 smallblock and shares parts and dimensions with it's LS cousins. Great engines.

lol you are correct BUT they do tend to get called LS engines wink

sorta like Beaumont and Acadians, that were a separate make, that eventually became Pontiacs (legally)

The Truck 5.3L

The basic 5.3L Gen III engine began its production life in 1999. In its base form, it comes as either an iron-block LM7 5.3L or an LM4 aluminum blockversion appearing in GM light duty pickups, Suburbans, Yukons, and vans, which means there are literally thousands of these used engines now in boneyards.

The original LM7 5.3 is basically an iron-block LS1 engine with a smaller 3.78-inch bore (the 5.7 is 3.89-inch) rated at between 285 and 295 hp and 325 to 335 lb-ft of torque in stock GM trim. These engines also share the 5.7L's 3.622-inch stroke, and some enterprising car crafters have built an iron-block 5.7 merely by boring the block to the 5.7 bore dimension and using a 5.7L rotating assembly (the cranks are different due to piston weight).

The stock 5.3L comes with a decent 9.5:1 compression ratio right out of the box and uses essentially the same cylinder head as its "larger LS1 cousin", but with a smaller combustion chamber.
