From my experience a 5.7 pre 09 is about 1000-2200 depending on how complete and mileage.

6.1 long blocks for 3000- and complete engines for 3000-6000. again depends on brand new to how many miles and what all comes with it.

personally a 5.7 block with a stroker would be a good street/strip bracket engine. just my imo, and others can chime in.

the 6.1 is just a bit harder to come by...
