A junk jard 4.7 is right around 1500 for a long block, but then there's that wonder when it will go bad. There is an issue with these motors I guess and all of them have the same issue at some time. They say that it's very costly to do a 5.7 swap from dodge. I was just asking cause he will be back from deployment next month and want to get it back on the road. I was thinking a 5.3 swap could go under 2 grand but Thot I'd ask some of you
