426 inch+ small blocks

Ditto on the failure rate. I think there is just a fair amount of core shift blocks being used and overbored without thickness checks being done prior to the build. The issue has been addressed on this site several times before. I met a downstater (from the Niles area) at Red Barn this summer (rained) that's running a K-1 4.125 w/6.2 rods and 11.0 cr in a 360. He drives it everywhere and has almost 10k on the engine. A local shop in Jackson MI built it and according to them dyno sheets showed 545hp. It's a lightweight rotating assembly (comparably) and he stated the stroker kit from Weisco was less than $2400. It was strictly a street driven car no cage etc. For what it's worth.....Sport
