Please Help Good deal or not?

if it was me i would wait until you get a more complete package, not all torn down, and even without a spun bearing. the core value of an engine block is maybe $200-$400. in my opinion this might not be your best option to spend your money. putting a 5.7hemi in an older car is expensive enough to start with... very expensive. and by getting something that is torn apart and half there you are putting yourself behind the 8-ball
