It is however undergeared for the 1/4 mile, that's why you see the factory stock 4V's that completely wiped out the 5.0's in the last two years running 4.56-4.88 gears. That's why they are handicappping 4v's next year to 3.90 gears, the fastest 5.0 factory stock efforts are at least 3 tenths and 3 mph slower than the fastest 4v cars. 3.90 gears are perfect for a 5.0 but extremelly undergeared for an all out NA 4V setup. Now if you have a forced induction 4V, 3.90's would be fine. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>hidnn.o.s.</b> <br /><small>Member # 1219</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(2005,11,13,19,55,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> "FACT,", IT IS ABSOLUTELY "NOT" WORTH IT TO SWAP YOUR 410'S FOR 430'S. If you had stock gears and wanted to upgrade all together that's one thing, but it would be a waste of money for the MINOR difference from 410's to 430's. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>1fast281</b> <br /><small>Member # 4670</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(2005,11,13,20,13,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Exactly, that's why I said maybe go for 4.56. The difference between 4.10 and 4.30 gears is only a couple hundred rpm so it won't be that noticeble on the street. At the the track, I would guess in a 96-98 Cobra going from 4.10 to 4.30 it would drop .1-.2 tenths in the 1/4 mile. Going from 4.10 to 4.56 probably at least 3 tenths. Don't fear the gear with the 4.6 dohc... <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
