Compression Ratio
On a 350/383 chevy with aluminum heads/intake. What is the max compression before spark knock occurs or turbo blue must be used? Some say 10.5:1 or 11:1, what is the real truth.

Pre-ignition.
Whats the piston design? Whats the volume of the head chambers? Typically,with an over bore and stroker,plus 6" rod application, your looking at more compression than a normal 5.7 rod config (350). My 383 is using 6" rods,flat top pistons, with 49cc Darts,and Ive been told by Lunati that I,m around 14:1....
