The displacement of the motor shouldnt matter. Not sure of the compression ratio to keep it at. 10 to 1 or 10.5 to 1 would be pump gas friendly. Dont forget the supporting mods too, (i.e. injectors, mass air throttle body.) Do lots of research and find carb numbers for external stuff. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>The TASM</b> <br /><small>Member # 292</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(2007,0,29,16,52,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Thanks, I will look for the parts that have CARB numbers.<br /> <br /> <small>[ January 29, 2007, 04:53 PM: Message edited by: The TASM ]</small> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>66backinblack</b> <br /><small>Member # 5372</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(2007,0,29,17,50,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> i remember the 347 i had built for me had a smog and no smog option, it was from ford racing. maybe somethin to do with the pistons? <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
