I'm not a pure engine head, but what I have learned or been told in the backyard is, that a 302 vs a 351w both can only be bored to 4.030" . changeing the stroke may effect the torque vs the increase in HP. The reason I brought this up is that you may save money going another way instead of a lightning setup and make the same results or higher with a 302 vs a 351w<br><br><br><br>http://www.kb-silvolite.com/page47.htm#SECT1<br><br>Ford 347: Ford 302 block with 4.030" bore, 3.4" stroke and 5.4" rod combination.
