Worth what?
They're just a reman engine pretty much equalling a stock engine.
I'm not being sarcastic. Just saying what you're looking at is nothing exotic, modified, etc.
If the price works for you with freight...freight with engines/trannies/axles should always be factored in as it's not a 6.95 USPS fit in the box flat rate cost....
If it works for you go for it.
