The ad says the springs are only good for a .530" max lift. Most cams list the lift based on a 1.6 rocker. If you want to know what the lift will be with a 1.7, you divide the lift number by 1.6 then multiply that by 1.7. Here's an example.<br /><br />The Ford E cam is listed as .498". .498/1.6=.311 (lift at the lobe)<br />With 1.7s it would be .311x1.7=.529" <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>CarlosLaz</b> <br /><small>Member # 11235</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(2011,10,12,15,54,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Ok well since I have a stock cam I should just go with 1.6 I'm assuming? <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>wilit</b> <br /><small>Member # 3367</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(2011,10,12,19,2,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> </font><blockquote><font size="1" face="Verdana, Arial">quote:</font><hr /><font size="2" face="Verdana, Arial">Originally posted by CarlosLaz:<br /><strong> Ok well since I have a stock cam I should just go with 1.6 I'm assuming? </strong></font><hr /></blockquote><font size="2" face="Verdana, Arial">Stock HO cam is .444" I believe. With 1.7's, you'd be at .471". So you'd be okay running 1.7's with those springs. <br /><br />What you really need to find out is if those heads are stud or pedestal mounts.
