Im in washington state, i purchased a 7.3 short block from kings of power stroke out of PA with a $1000 core charge. After calling him to get my refund he changed the core to $600 cause he says they are moving and he lost my invoice. so i sent him a copy of my recept. now i cant get past the receptionist. Aaron Davis is always to busy to talk. he's a peice of work. I hope i dont need a waranty. thats suppost to be 1 year unlimited milage. So look out for these guys,pass the word on. And if you happen to no them kickem in the junk for me please. Does PA have a better busyness bureau? my lesson is buy local so i can kickem in the junk my self.
