what year? If it is EFI you will only use the block and heads. The timing cover, pan, intake, distributor, carb etc would be different. Probably not worth 575 if this is the case.
Around here, that's a decent price. Considering it's a 16 year old engine, and there arn't many 16 year old cars around.
Again, what parts will you actually use E7 heads $50 HO short block $250 maybe some accessories and brackets $50-75 Don't think it is worth the 575 I realize this may not be local for you but local pickup can't scare up 99 bucks (with 35 mintues left) http://cgi.ebay.com/ebaymotors/1987...ies?hash=item19b6bd03e7&_trksid=p4506.c0.m245
