The “LME blower engine” in Cleetus McFarland’s context is a Late Model Engines-built blown LS-based V8, set up for hard burnout use with a Roots- style blower on top. In the recent video result, it’s described as a 427 cubic-inch burnout engine making about 1,130 horsepower and roughly 900 lb-ft of torque on M1 fuel.

What “LME” means

LME stands for Late Model Engines, a performance engine builder that supplies custom high-power combinations for drag and burnout applications. In Cleetus’s case, the engine is built specifically to survive abuse rather than just make peak dyno numbers.

What makes it a “blower engine”

A blower engine uses a supercharger mounted on top of the intake, forcing more air into the engine for more power. The one referenced here uses an 871 Roots- style blower with a looser setup than a pure drag race combo so it can tolerate throttle on/off transitions during burnouts.

In plain English

So, if you’re asking “what is it?”: it’s basically a very stout, supercharged LS engine package from LME built for Cleetus’s burnout cars and other loud, high-horsepower projects. A simple way to picture it is: big cubes + big blower + burnout-proof parts = outrageous torque and smoke.

Context from the latest clip

The most recent result ties it to a 427-inch build that was dyno-tuned and ready to rip, aimed at burnout use rather than road manners. That lines up with Cleetus’s usual style of overbuilt, entertainment-first muscle machinery.

TL;DR: it’s a Late Model Engines 427 LS-based blower motor, built for Cleetus McFarland’s burnout antics and making around 1,130 hp in the recent setup.
