spotfitz Posted July 10, 2003 Share Posted July 10, 2003 I located an E31 head that has been rebuilt, but with all original equipment(basically stock), except a moderate cam. The springs are original, but everything else is new. What would be the going rate for something like this. It has never been bolted back on a block. I want to purchase it, but don't have a clue as to what a good offer would be. Quote Link to comment Share on other sites More sharing options...
Guest zline Posted July 10, 2003 Share Posted July 10, 2003 depends on the cam - has it been milled? stuff like that I'd offer $100 for it if its just stock with a pretty weak cam. Quote Link to comment Share on other sites More sharing options...
gramercyjam Posted July 10, 2003 Share Posted July 10, 2003 You should probably find out exactly what was done to it in the "rebuild". I can tell you I recently paid about $325 to have the following done to an E31. I did plenty of checking around first and this price is considered cheap around here for head work. Pressure test head Straighten the head - shave top and bottom surfaces to my spec: all new intake and exhaust valve guide inserts all new oversize valve seats fit all new oversize valves 5 angle valve job Thats it. I bought all the parts with me so the machine shop didn't need to provide any parts and I did all the disassembly and reassembly. The most expensive part is putting in new oversize seats. Machine shops don't like to do it because there is too much room for error and screwups. Replacing with the same size seats would probably have been $100 cheaper. Of course the turbo/EFI crowd is not the market for this head. I think it would be worth considerable more than $100 if it really has had everything it needed done to it. --John '73 FP 240Z Quote Link to comment Share on other sites More sharing options...
spotfitz Posted July 10, 2003 Author Share Posted July 10, 2003 I just so happen to have the bill sheet from the rebuild. Teardown, clean, glassbead and inspection. Install int. and exh. valve seats. Polish valve stems. Surface -.010. It has a Crane "performance" cam. I'll try to find out exactly which one later. Z Club meeting tonight, so.... Oops, found it before I left. This is the cam spec sheet from Crane: http://dab7.cranecams.com/SpecCard/DisplayCatalogCard.asp?PN=168-0012 Although this doesn't go along with the numbers on the sheet I have for the same part number. Go figure. Here's what the sheet says. 292 @ .450 int. 292 @ .450 exh. advertised 272, 282 duration Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted July 19, 2003 Share Posted July 19, 2003 Hmm looks like I need to sell that head to someone. That cam is in the vb catalog for 389.95 supposedly the list is 487.44 sure not a small block chevy price. Quote Link to comment Share on other sites More sharing options...
