Crate engine ??

[idaho66stepside]

I found out the 350 I just put into the 66 stepside is F'ed. Bad crank, maybe block don't know the full extent of the problem. But I do know it's cheaper to get a crate short/long block. Have any of you guys have some experience with engine wharehouse in auburn WA, or ect engines in Houston TX. What about the good ol' GM performance engine. Budget is pretty tight 1500 maybe a little more. The local engine builder is mighty proud of his work and I'm not sure his work is any good. Any help would be great Thanks!!
