Windsor engines have 13 or 14 bolts ( don't remember exactly) Romeo engines 01-04 have 11 bolts. I recently blew up my 04 engine and used a 96 short block and some MMR heads, I used the same flywheel I had on my 04.<br /><br />Short answer if you use a romeo block you need to grab a flywheel everything else is interchangeable <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Saleen 00-768</b> <br /><small>Member # 9379</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(2015,11,21,13,9,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> The types of differences between these years shouldn't matter much in regards to a swap.<br /><br />Adding to differences already mentioned:<br /><br /><br />99-early 01 are Windsor engines and 02-04 are Romeo engines.<br /><br />99-early 01 uses full floating wrist pins, 02-04 are pressed.<br /><br />99-early01 use a (better) 10.5" clutch & 8 bolt flywheel, 01-04 uses 11" clutch and 6 bolt. McLeod makes a flywheel to allow an upgrade to the 10.5" clutch<br /><br />99-early 01 use t45 trans 02-04 switched to tremec tr3650<br /><br />99-early 01 have different length water pump shaft meaning they use different pulleys.<br /><br />01-04 has the updated intake manifold w/ aluminum coolant cross over<br /><br />99-01 also uses a different type of maf sensor with an external air temp sensor placed into the intake tube. in 2002-04 has the sensor built into the maf meter. (For motor swap, use the same year maf as Your car NOT the motor)<br /><br />Late 01-04 switched to 21lb injectors from 19lb on 99-00<br />(Use the injectors that match the year of the car NOT the motor)<br /><br />The 99 4.6 uses a 3 bolt belt tensioner with a longer belt than 00-04<br /> <br /> <small>[ 2015-12-21, 01:19 PM: Message edited by: Saleen 00-768 ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Kb69fastback</b> <br /><small>Member # 13054</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(2015,11,21,16,9,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Wow you guys are very helpful.
