I've got a 2000 Yukon 1500 XL with a 5.3 LM7 engine. It has 245,00 miles. It looks like it just threw a rod. Summit wants $4270 + $2500 core for a GMPP reman. LKQ's best engine has 144,00 miles for $635. Engines Direct in AZ wants $1900 plus $300 core for a reman. Does anyone have any experience with Engines Direct?
