I don't know who figured your static compression ratio or how it was figured, but it's wrong. A 383 with 5cc valve reliefs and 64cc heads will be 11.14:1 static compression ratio. You'll have to run a ton of cam even with the tight squish to keep the motor out of detonation. A ton of cam ain't gonna be much fun in a street motor. I suspect you'll need around 245 degrees @ 0.050 which will give you an operating range of 3,500 to 7,000. You'll need a converter that stalls at 3,500 minimum and a rear gear somewhere in the 4's.
Also, stock iron heads are a bad plan.Last edited by techinspector1; 03-23-2009 at 02:29 PM.
