The lifter dogbones are a dead giveaway as well.Looks like you got yourself two boat anchor E6 heads as well. :hick: Quote Selected
Project Evolution *** Project Complete **** Wednesday July 9, 2014 Reply #1786 – January 06, 2010, 08:09:52 AM I read somewhere that the xxx is the location where they were manufactured, as some people said they had non-roller blocks and the xxx on it. YYY blocks were said to be manufactured in Mexico with a higher iron content compared to the XXX blocks. I don't know if there's any real truth to that though. I'm going to keep searching for the real answer, be it location, or block type. I notice there's a lot of bad information out there about Mustangs, motors and modding. It's tough to know what to believe sometimes.Does anyone have a pic of a non-roller motor? It would go good in this section of the project thread, as a comparison of the 2 Quote Selected

Project Evolution *** Project Complete **** Wednesday July 9, 2014 Reply #1788 – January 06, 2010, 09:41:36 AM Left is a roller lifter - which makes it a roller block.Right is a flat tappet lifter - which would make it a non-roller block.Roller blocks typically have the top of the lifter bores machined flat for the dogbones to sit. The dogbones and the spider keep the roller lifters in alignment with the cam. Quote Selected

There would be less lifter bore on a non roller. Just build it, Quit stalling!! Quote Selected

Project Evolution *** Project Complete **** Wednesday July 9, 2014 Reply #1797 – January 10, 2010, 10:17:53 PM I would imagine they would be the same as the big three cylinder air compressure motors from locomotives I used to tear down. But I think the cross hatching is a factory marking from them being machined. I know if a cylinder had it it was still in good shape. But if it was worn off it usually ment the piston or ring detoriated and sed them off. So I would think you'd want to see that on them. I'm not a mechanic or a machinist but I kinda learned that from experience. Quote Selected
