Do you think I got screwed, or is it just part of the hobby?

My opinion is to bring them back the shortblock,once they disassemble and see/find your problem they should warranty their work.Your going about this the right way as to your calls,enquiring and following their steps to see if the problem goes away.which it hasn,t.My engine builders are mainly Ford,Chebby guys,but are now doing alot of Mopar stuff with good results,me being one of them.If I had any problems right off the hop,they would,ve stood behind their work.It makes good for more business.Good luck and keep us posted with your results/findings,it might help someonelse down the road.:read2:
