Now, if we are considering a Speed-Pro H116CP piston, which has a compression height of 1.670 inches, we add that in to get 9.583 inches. Since an uncut Mopar small-block cylinder measures 9.600 ...
“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...
Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...
