74,000 miles. All aluminum 6.0 engine with 400 hp and 400 lb./ft torque. 100 lbs. lighter than an iron block LS. Recently purchased from Grand Valley Auto Parts on ebay for a project that I cancelled. The engine is clean and includes the accessories, sensors, harness, ecm, and gas pedal. I have not installed or run it, but Grand Valley Auto Parts has a solid rating and reputation. I bought the same engine from them awhile back for a project and it runs beautifully and has great power, so I would expect the same from this one. $4000 obo. Call or text Chris at 801-898-1631. Thanks for looking.
