LS7 442ci Dry Sump Stroker Engine Pullout


This was a custom build. Customer Spent $20k having this engine built and installed. It has right at 3k miles on it since the build was completed in September of 2021. 

Description

For Sale is a Used 2013 Corvette LS7 Aluminum block 800HP complete engine pullout. This setup is in excellent condition. Setup has only 3,000  miles on it since it was built!!.  Pulled from a very nice C6 Z06 427 edition Corvette that caught fire. This auction includes all parts shown. Complete engine from pan to intake, all belt driven accessories, all engine sensors, starter, pedal with pigtail, Dry Sump Oiling Tank, Oil Tank Lines, Tuned Engine Computer.  Etc. This setup would be a lot of fun in any street rod wanting a reliable fuel injected setup that packs that nasty punch when you want it.  All fluids are drained.


Engine does not come with a wiring harness, or the ignition coils. 


These LS7's are no longer produced or sold by GM. 


We have the install paperwork from Redline Performance for the install of the top end of this engine, as well as the install of this into the donor vehicle. The bottom end of the engine was built by PTS Racing Engines out of Minden, LA.
