whats a slant 6 worth ?

agree with the above. if it's a super solid motor that starts right up, doesn't smoke or make a bunch of noise and the trans is smooth? mayyyyy-be $500 to the right person.

but like others have said, a complete is a hard sell and you might sit on it awhile. if you break it, the pieces could move pretty quick and you'd probably get that 5 easy.
