LS7 LATEMODEL ENGINE
The LS7 makes a great engine for a dirt latemodel.  We have made serious strides since we introduced it in 2020.  Our latest changes to the front of the engine makes it the most compact engine available today.  We are 5-6″ shorten than a ford, & 2-3″ Shorter than a Widebore.  The engine is light as well.  Fully Dressed we are under 345 lbs.  Besides it being light and short, the engine is an absolute Power House!  We have set overall fast time at Lucas Oil Shows on 6 different occasions with regional racers.  That shows the the power is there.  These are on bigger race tracks as well.  With all the latest changes to the cooling side of the engine, we are seeing cooler temps than anything currently on the race track/  We have made strides in the driveability as well.  Our latest Billet Manifold has helped with restarts and taking the surge out of the powercurve on the slick tracks.
