| − | Some engines used a steel ball instead of a cup plug. These engines are the 1986-up 1-piece RMS blocks including the Gen 2 LT1. These blocks can’t be tapped for a 1/4” NPT plug, the hole is smaller than the 1/2" ball or cup plug used in 1985-back Gen I SBC blocks with 2-piece RMS. The part number for these '86-up 1-piece RMS blocks is Pioneer '''EPC108'''. | + | Some engines used a steel ball instead of a cup plug.

| + | ==Checking block for plug== | ||
| + | If there is any question whether the plug is in place inside an assembled engine, a straight piece of wire can be used (like piece of brazing rod) to check the depth of the plug in the block. By going down the oil sender hole at the rear of the block, the plug should be located between 8-3/8" and 8-1/2" down. If the rod extends down further, that would indicate the plug is missing. | ||
