Gen 3 LNF Short Block

SKU: ZZ-LDKSB

$1,399.99 Sale price

Regular price $1,399.99

The Gen 3 block is a huge improvement for GM and solves previous shortcomings of the Gen 1 & 2 versions of the Ecotec motor.  In fact, the Gen 3 block itself supports over 500WHP in stock form, however the rods cannot support over 400whp.  So to make more than 400whp we would suggest better rods and pistons.  We offer a full forged engine here.

Improvements include:
-Cylinder wall bracing that prevents sleeves from breaking out in high HP applications
-Sand casting which removes porosity found in the older foam cast Gen 1 and Gen 2 blocks
-5 pounds of additional aluminum adding internal structural support and solves the coolant jacket leakage issues with Gen 2 blocks

No core charge.

This is a fully assembled short block, includes block, bearings, crank, pistons, & rings assembled as in the picture. Does not include the water pump, timing chain assembly (guides/chain), or the front cover. The "LDK" option comes with the oil pan and dipstick tube.

Important break in procedure:
We recommend running
Comp Cams "break in" oil for the first 200 miles. Before you start the car with the new engine, we recommend that you fill with oil, then leave the injector harness unplugged and turn engine over until the oil pressure light goes out, or even better, use an oil pressure gauge. This ensures that you are starting the engine with full oil pressure. 

When the engine is running in gear and at light throttle, bring it up to 4500rpm, then coast down to near idle(still in gear), then 5000, then 5500, then 6000, and 6500 each time letting it coast down to idle. This will help seat the rings. Then after a couple heat cycles, start running it under power.

LNF BLOCK

Great block. Just by looking at the block you can see the higher quality (no foam mould markings) and it's very well built. Comes with pistons and rods, but it's very easy to replace them with forged ones. Takes a lot of time, but it's not difficult at all to take apart the engine and replace the blocks.

LNF Gen3 Short Block

ZZP was great to work with on a short notice request. We were able to reassemble the engine and race car and get it back running in less than a week.

Amazing Customer Service

So, we bought the wrong engine... it was entirely our fault (not paying enough attention). We had some very odd circumstances with this engine swap: the car was in Austin TX, the owner was in El Paso TX (9 hrs away), and the money was in Coeur d'Alene ID. Add to that, the owner was military and out in the field, unreachable, the bulk of the time. By the time we figured out the mix-up, we were way past the return policy deadline. We explained the situation and ZZ Performance totally worked with us to get the engine exchanged, with only a nominal restock fee. They even cut us a check for the difference! These guys are great - if you're considering a rebuild or upgrade, shop them first. Top notch, I cannot say enough great things about them!
