    Rated 5 out of 5 by from Just as advertised . . . I purchased this engine for my 1998 Chevy Tahoe 2D. It was a plug-and-play factory engine replacement that performaned excellent. I highly recommend this replacement engine, you cannot go wrong. I had mine painted in hanger orange as and to history; I only wish the engine came in that color straight from JEGS.

    Rated 5 out of 5 by from Another good product from JEGS I purchased this GM crate engine to replace the tired old one in a 96 Chevy Truck. Item was shipped fast and packaged well for shipping. Very impressed with the quality and craftsmanship when removed from crate. Installation was very smooth and the truck runs great with way more power than it ever had before. Thank you for the quality products and service once again JEGS.

    Rated 5 out of 5 by from Excellent "New" Replacement Engine Just like the original Vortec in my '97 Chevy K1500. Waited awhile to write this review to make sure the engine was fine. Just did my first breakin oil change at 500 miles. This engine is running smooth. Cold start oil psi at 70. Once its up to temp the oil psi is steady at 60/65 running 65 mph at 1800 rpm's.& 50psi at idle. No leaks at all. Plenty of power. Will only get better over time. So glad I went with the new GM engine instead of a rebuilt. With regular maintenance this engine should go 200000 plus & well outlast my old truck. Jegs has a great deal here, great customer service and the free shipping was a added plus. Very happy so far !!
