Can I get some help from you 5.0L experts?

block is the weak link not the bottom end. block is safe to the 400whp mark, after that its a time bomb til you split it down the valley down the middle. the heads are like breathing through a coffee stir stick, the are horrible. I think that they will restrict you from running enough boost to hurt the motor.
i think you can hit mid 300s to the wheel on a stock motor and 15+ psi of boost

It's all in the tune.....and like Tim said don't over-rev the shit out of it.
There no saying its safe to run 550 through a stock 302 block, Ive heard of them lasting with levels around that and ive heard of them splitting around 450, its hit or miss, as stated try and keep the rpms down. a girdle will not help the strength of the block it will only keep the parts together when the block splits. go with a 351 block, dont waste time or money with a 302 block unless its aftermarket.
A buddy of mine just dynoed his 93 Cobra with stock bottom end, Steeda #19, GT40X heads, ported GT40 lower, and the small old 1.5 Kenne Bell and got 437rwhp and 497rwtq with around 10lbs of boost.
I ran 11.75@119 with a 1.5 back in '01, just heads/1.7rr's all stock bottom end and cam.
But overall, I'd go with a Vortech or Paxton, or a Procharger.

There are alot of cars in the low 10's to high 9's stick untouched bottom ends. A guy on Corral was running 10.1 with a completely stock shortblock INCLUDING cam with the smaller SC-Trim Vortech. He even had the old school GT40Y heads. All about the total combo and the tune. Keep the timing to a reasonable level and it will last longer.
