His calculator is real close to mine though(I found it after the post). < Message edited by GRIFF -- 10/17/2006 3:47:39 PM > (in reply to shnormo) Post #: 22

RE: Roll Cage - 10/18/2006 3:19:41 PM    GRIFF   Posts: 781 Joined: 9/3/2006 Status: offline Sorry I messed up used the wrong stroke should have been 12.5 @.025 deck/13.5 @0 deck depends on head gasket thinkness, ring lands, true chamber volume. Again sorry about that. GRIFF (in reply to shnormo) Post #: 27

RE: Roll Cage - 10/20/2006 4:04:41 AM    uncle bill   Posts: 819 Joined: 9/3/2006 From: San Antonio, Texas Status: offline The expandable foam is a great idea. The 230's are too big a runner for a 383, Won't make any power below 6000RPM, too much air tumbling and not enough airspeed. VP C16 is the best fuel out there for a Rael high comprecssion engine, massive amount of hydrocarbons slowing the burn rate. Hope this helps. (in reply to GRIFF) Post #: 29
