5.0 most HP?

[angcobra]

What is the most HP anyone is running on a stock 5.0 block?
The dyno numbers show i overshot my goal for HP and now I am concerned about splitting the block. I hate to think of running NA when everything is setup for FI.
I would like to know the highest HP anyone has on the stock block and it is still running.

600hp with main girdle

600hp with main girdle

Is that 600 at the crank or RWHP?
How long have you been running that?

Around 500 (without girdle). It's really going to depend on the tune. If you have a solid tune and things are working properly then it'll last longer.
