I just replaced the 4.7L engine on my 99 GJC Limited and I have the old block with internals. Is anyone around in need of the block or a rebuilt engine, because I am planning on rebuilding this engine? I don't feel like putting the effort into putting everything back together with the old parts in order to get a $400 core charge back. Please PM me if you are interested and we will talk price. I am not interested in making much on this, especially for a fellow Jeeper, I just want to get my money back. Thanks!
