No they aren't... they are hyperutectic pistons, they stopped being forged back in the fox bodies

I believe 1992 was the last year for forged rods and pistons.
Stock crankshafts in the pushrod motors are cast. If you don't have detonation, the crank may handle 800-1000 HP.

Probably not. I've seen some stock blocks run 600rwHP and other crack with way less and detonation. I use JB weld or metallized body filler in the webbing to strengthen the stock block.

My buddy with 800hp Incon TT kit + no tune + spark knock = broken crank + block.
Dyno tune would have been a bargain! Hopefully I'm learning from other's mistakes. 25k blown miles on stock block so far. Fingers crossed!

Probably safe. The weakest link in a chain breaks first, same in our mustangs. In my situation, the throwout bearing and clutch went south first, then the rear trak-lok turned into a one-wheel wonder,etc,etc. I can't say enough about a safe tune though.
