Did you even hear it run? Sounds like no considering its missing a lot of vitals. Also, what heads are on it and how did you determine it needs seats? Is this a fresh shortblock or something thats been rebuilt and has miles on it? And even though you dont know the cam specs, how do you know its a big cam.....I assume you heard it run at one time and could hear that its got a healthy cam.....but then again, it also sounds like your dad just picked it up and somebody may have just told you that its got a cam in it.
2500 is sounding real steep. From what it sounds, it needs a top end(needs a manifold, has heads but they need done, and who knows about the cam and everything else for sure....so, it basically needs a top end). It sounds like its just a shortblock(that may or may not be fresh) and I wouldnt pay nearly that much unless there is real good stuff throughout the bottom end and the machine work/assembly has really been done well. List more specifics cause its real hard to tell anything right now.....could be worth more than 2500(possible)..... but I get the impression that its either an unfinished rebuild, or a rebuild with miles(wouldnt be surprised if it had a stock rebuilt bottom end either). If thats the case, Id say it would only be worth maybe 800 bucks to me if it was indeed a complete shortblock thats gone through a descent mostly stock rebuild at one time or another. If its got considerable miles on the rebuild, I woldnt even pay that much. If its good enough to use for a mild performance application, Id give roughly 600 for the shortblock and then put my own top end on it. But I might pay say 1200 bucks if it is a fresh shortblock with new, good rods and pistons(and of course the work is well). What casting number is that block and is it a 2 or 4 bolt?
Anyways, for it to be worth 2500 to me(especially since it needs a top end basically), it would have to be an excellent, fresh bottom end thats done right.
