First off it says 4 bolt main and is 2 bolt 289 casting. told me it had JE pistons in it and are trw, suppose to be eagle crank & rods and are gm i beam rods and cast crank. Pick up the truck in March and went all the way to him. Went to freshen motor up and what a suprise! Make sure it is what you say. That is why i am bitching, you lied , because you didn't know at all what you had!!!!!!!!
