Are 5.56\" rods really THAT bad Are the stock 5.56" rods in 400s as bad as everyone gets worked up about. I got my 400 in the shop and started to disassemble it. I was expecting wear city from all the hype, but that was not the case. The odometer showed a little over 100,000 and the bores hardly had any lip to them. You could barely catch your finger on them and the motor had never been overhauled before. For as dirty as the outside was, I suspect regular matience for as clean as the lifter galley was. I'm gonna make a 404 (.020 over) that'll run about 400hp on the dyno. The computer shows I'll have that at about 4,700 rpm. Now thats one low winder! If I could keep the stock rods, I could run the stock style pistons. Which means a 9.3:1 squeeze with 64 cc heads and keeping the balance near stock. That means no rebalancing, no clearancing, ALOT more affordable, and good compression. You can not find a lower compression hypereucraptic piston for a 5.56" rod, so I gotta run cast. Seeing as how this will be a daily driver, I don't think forged would be in order (cold slap, cost, throwing off balance) and could be fine with cast. Basically I wanna build a dependable street engine that I can afford. It'll get clevite bearings, ARP bolts, and that stuff, so its not a total cheapskate special.
