feeler- merlin 540/tremec tko600 value

[Bsinclair]

im looking at purchasing a builder car with a brand new merlin 540 and tremec tko600. since im wanting to do a ls conversion im thinking about selling the combo. any idea what its worth? the motor has start up run time only and the trans 0 amount of use. the merlin is a steel headed version and was $10500 when it was purchased.. i may decide to keep the tko but wont break them up until i sell the motor first. the package woud include the clutch and bell housing. any insight would be helpfull
