The bottom line to all this is it's best to maintain an adequate quench figure of 0.040". There's nothing to be gained by going tighter, and a 0.040" quench distance will avoid unseen problems for the most part. If the quench is less than 0.040", be sure to double check clearances to be sure there is no contact between the piston and head- for obvious reasons. | The bottom line to all this is it's best to maintain an adequate quench figure of 0.040".

| − | Next, if using a standard 5.7" rod length, use a piston with a 1.560" piston compression height (measured from the centerline of the wrist pin to the top of the piston crown). Now, if we add up all the dimensions of our "stack" components, we find that we have room in the block for them, plus a little extra which will be between the crown of the piston and the block deck. 1.740" + 5.703" + 1.560" = 9.00". So, if there is 9.025" available and the stack is only 9.00", that leaves 0.025" space above the piston crown with the piston at top dead center (TDC). This space is called the '''''piston deck height''''' (not to be confused with ''block'' deck height). | + | Next, if using a standard 5.7" rod length, use a piston with a 1.560" piston compression height (measured from the centerline of the wrist pin to the top of the piston crown).
