main cap walk

No problem. My stock main-capped 340/416 stroker with light ESP Eagle rods and lightweight Diamond dished pistons had cap walk too, but I suspect it had some detonation issues on pump gas (89-91) and street driving. Used ARP studs on it as well. Zero main bearing wear issues and I was able to reuse the rod AND main bearings upon inspection/freshening. Mild cap walk, but discernible.
