Sinter forged and true forged for the connecting rods are not the same. Boss 302 rods are about $40 a pop. Manely H beam rods are about $100 a rod.
Factory rods were ok for stock to mildy modified. No way would I pop a blower on a stock 5.0 without it being factory warrantied. At least not until true forged rods were installed, then thats a different story.
