so if i were to get a 92-93 5.0 i can get away with HYPER pistons right? I also heard that the rods were FORGED for those years? this true?

i am planning on having it well built because i am going to be dropping in one of those KENNE BELLE blower kits for the 5.0's

i just wanted some info, so i can justify in spending the extra money on forged stuff!

well you dont want anything stock anyway you should look at stroking this engine , its cheaper now than doing a stock overhaul .

Rods

The stock rods are forged, but they are not something you'd want to go beyond 350 HP or so with. They have 5/16" bolts which typically are the weak link. I've seen them go higher (in power level) but when they fail they take out everything. We've run 'em in a round-e-round class for a while and we're making 325 HP but when we tear the engine down for a freshining the rods require rework, granted we're running 'em at 6500 RPM for an extended period of time.
