I ordered a new dip stick and tube from Mancini racing. The tube is 12 inches long the one that came out is 8 inches long. I went to the garage and measured the one in my dart it is also 8 inches. Mancini says they sell tons and nobody complains he swears its correct for a 340. Has anybody run into this or do they make different length tubes and sticks for small blocks? whats in your small block 8 or 12 inch(insert joke here)tube.
