SB Rod part #'s query

Toplscuda - that's a strange one -looks like parts in the wrong box, or a mixup (or dishonest? unless they were nos from a dealership). Well i think you definitely have the HD rods, the 645 were the heavier ones. But the 495 Part#...according to 2Darts list above, the 496 is the HD version of the 495. Someone else told me the 496 might be the DC (Direct Connection) race version. Too many numbers, all too confusing! There are some really nice light new rods available now, brand name EAGLE and SCAT I beam rods can be bought for around US$300 or less. I bought some SCAT rods from KMJ Performance from Ebay, Mancini has some Eagle I beams for under $300. Of course they are made in China, like almost everything now days, but they are name brand and the SCAT ones i bought are very well packaged, machined in USA and are all very light, about 100g lighter than the stock ones, weight matched with ARP2000 rod bolts ready to fit.
