I can get a used 350 from thirdgenresource.com for $1250, and a TPI setup(from the MAF sensor to the intake manifold) wiring harness, ECM and fuel rail/injectors for $600. I figure with shipping($300?) and installation($500?) plus $850 of unknown complications and it will come to like $3500 high ball. If I get better deals on a local engine then it could be more like $1500 total low ball. Are these figures pretty acurate? Am I missing anything?
