Product Summary
- LS3, Long Block Crate Engine Type, 473 ft./lbs. Torque
LS Classic GMLS9005 LS3 details
All of our LS Classic components are available, installed, on one of our Classic Crate Engines. We start with a brand new, GM 495 horse power LS3 right out of the box and with a two year warranty. We then paint it orange (if you so desire) and begin assembling your desired components until we have the perfect crate engine for your project. Once completely assembled we put the engine on our in-house run stand, load your Holley EFI ECU with our start-up tune, and run your engine to check for leaks and oil pressure. After we are satisfied that your engine will operate with no issues, we put it back in the original GM crate and ship it directly to you or your builder. Once you receive your engine it is as simple as installing the engine, routing the Holley wiring harness, terminating a couple of power and ground wires, and putting fuel pressure to the engine. We guarantee an easy start up!
