Another surprise.

I've never seen washers used with the stock main cap bolts either. They are listed as Mopar performance bolts. I don't know who makes bolts for Mopar or if these are even the real deal. They are sold as such and they come in a Chrysler plastic bag. The washers are large-diameter, they fit loosely under the bolts. They're too large to set under the small bolt head at the top, the small bolt up top falls right through the center of the washer. Later today I will be able to put them side-by-side the bolts that came in the motor originally. They don't look anything like ARP bolts and they don't look like factory bolts either. I was wondering if anybody had used this package before and seen this. They seem to be sold as replacement high performance 340 windage tray attachment bolts. Mancini racing has zero knowledge of them even though they sell them. I'll take pictures of them later today an attempt to post them. Hopefully somebody has seen this before. Maybe someone has a line on actual 340 bolts?
