As for the intake... your choices are the cobra/GT40 intake with a 351W lower if this is a TRUCK motor. If its a mild performance motor, look into the performer RPM with the 351W lower. If its a medium to hot performance 351W, check out the Trickflow 351 R intake. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>rokcrln</b> <br /><small>Member # 2536</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(2003,2,7,16,59,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Now on the intake who sells them and is it just a lower off a 351 will bolt to the 5.0 top or a whole different animal. <br /><br /> Wasn't their a saleen that came with a 351 and EFI?

I already have the 351w in my car but I am redoing the top end. I am going with a Coast high performance spyder intake. There arent many intakes available unfortunatly for the 351w. But just like any other motor, you have to decide what you want the motor to do. Supercharged, N/A, N20! Streetable or full race? It sounds like you already have a healthy long block. Do some research on what intakes opperate in your power range and meet your needs. I found the spyder worked the best for me, comes with custom fuel rails, any bottom intake you want( they use carburated 4barrel intakes converted to EFI )! <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" /> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>rokcrln</b> <br /><small>Member # 2536</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(2003,2,7,20,57,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Thanks for the info to all that answered. I have not yet decided on what motor to do. I have the 351W that will take a few mods to get in the car the way I would want it. Then I also have a 92 OMC Cobra Marine 302 that yould make a geart base for a blower motor. It only has 10k on it and is a high nickle block, steel crank, forged pistons, beefed up mains and HD rods and it would be a bolt in and so would all other parts. <img border="0" title="" alt="[Confused]" src="confused.gif" /> <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
