    Rated 5 out of 5 by from Great Products I purchased this L31-R 350ci long block for my 1998 Chevy k1500 Z71 4x4. I was very pleased with the packaging. Since i don't have the vortex on it and being a high performance guy i was a little disappointed with the output horse power with my truck being a 4x4. other than that, i'm pleased with the engines smooth running and dependability. Over all very happy with my purchase. Thanks Jegs.

    Rated 5 out of 5 by from Very Happy with service and product. There were a couple issues with initial purchase approval but there was good communication with "real people" that made it all work out. The engine arrived VERY well crated. It was put in the truck and has been running perfectly every day for last couple weeks. Mechanic was so impressed he is recommending others to buy from JEGS.
