pparaska Posted October 14, 2003 Share Posted October 14, 2003 Kevin, that was very well put. Those 305 AFR heads were part of that engine's success. Heavy Z, that's a great point. With the 6.209" rods and the 3.25" stroke, and a block at the standard 9.025" deck height, a 1.19" compression height piston would be needed. That's a fairly tight ring package. But not as tight as the 1.125" comp height my 6" rodded 406" engine has. It's a trade off though - less side load from longer rods vs tilting of the piston due to the short compression height. I doubt I'll get more than 50,000 miles out of the 406 before something else goes in anyway (Like an LS6). Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted October 14, 2003 Share Posted October 14, 2003 I would also add that the Cyl. Heads & Intake Manifold used for the SBC Chevy Should've Built article were Aluminum...not Cast Iron. If you attempted to build an engine w/those high DCR & SCR's to be ran on today's pump gas, chances are you would experience Detonation regardless of which rotating assemblies are being utilized.
