We are attempting to build a (semi) streetable race motor for our 3. It has a Crane 244-310-8 cam, and the head has been ported and is running big valves, so we are figuring the compression should be in the 10.5-11.5:1 range. It has H-beam rods and a worked crank, but we will still keep the revs under 6500 in an attempt to keep it all in one piece. </div><div dir="ltr" data-setdir="false">There seems to be very little info on what people are running for race pistons floating around on the net. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks!</div><div dir="ltr" data-setdir="false">Jake & Karen Jacobsen </div></div><span>_______________________________________________</span><br><span>fot@autox.team.net</span><br><span></span><br><span>http://www.fot-racing.com</span><br><span></span><br><span>Donate: http://www.team.net/donate.html</span><br><span>Archive: http://autox.team.net/archive http://www.team.net/pipermail/fot</span><br><span>Unsubscribe/Manage: http://autox.team.net/mailman/options/fot/gblake58tr3@icloud.com</span><br><span></span><br><span></span><br></div></blockquote></div></body></html>
