What and when? What is the correct engine casting numbers for a BOSS 302 block? What casting date code ranges should be on a BOSS 302 block? A1: My car 9F02G194310 has its original block which is a C8FE casting. These are the race block castings not machined for dry deck. These blocks were used for a time in place of the C9 castings. I read that late '69 cars were built with D0ZE-A blocks. This is possible since I have a D0ZE-A block cast in late June 69. A2: Casting numbers on a BOSS 302 should be C80E-6015-B, C8FE-6015- B for early ’69. C9ZE-6015A or B or D0ZE-6015-A for ’69. D0ZE-6015-B for ‘69&’70. D1ZE-6015-B for service block. Example of date code in casting C9ZE is C meaning the decade, 9 meaning year, Z meaning car line, E meaning Eng. div. If the engine is originally installed it will have the Mustang’s partial VIN stamped into the rear of the block, just above the area where the bellhousing attaches. Example is 9F02G196957 will have 196957 stamped into it. Up front a small flat area on the driver’s side carried another code that identified the engine build date. Several digits appeared only the first two decode as the date. The first digit is the last numeral of the year. For example, 9 is 1969, the second is the month. Example A is January.</font><hr /></blockquote><font size="2" face="Verdana, Arial">Personally, I think Boss blocks are over rated and not worth the hype. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Norcalbmxer</b> <br /><small>Member # 235</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,1,7,13,26,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> 2 302 blocks......well 3 if you count the hecho en mexico block...<br /><br />xxx and yyy .....this only determines which factory the block was made at.... <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>SIR Paint Job w/ '84 Tercel Sr.</b> <br /><small>Member # 1708</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,1,7,17,28,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> personally I think any factory 302 block is crap<br />if you plan on making power, they fall apart over time <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>shade-tree</b> <br /><small>Member # 298</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,1,7,17,30,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I dunno, they are better than 305 TPI/TBI 'maros <img border="0" title="" alt="[Wink]" src="wink.gif" /> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>5PT SLOW</b> <br /><small>Member # 638</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,1,8,9,4,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> XXX markings on a 302. as sometimes you would see YYY. the block you were looking at was out of a cobra and the markings where more spaced out and marked at a different location then where you would normaly see the XXX marked.<br /><br />no one said anything about the XXX meaning it was a cobra block. i just pointed out that they were located in another location and were spaced out.<br /><br />and the fact it came out of a cobra. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
