I bought a 440 based 493 stroker kit from an individual and these bearings came with it. Mains are Federal Mogul part #119M and the rods are Speed Pro part #7135CH. Will these bearings be OK on a mostly street driven car or will they have a short life span. From what I have read they won't last as long as some other bearings and aren't the best choice for a street-strip car. Any help would be appreciated!!!!
