Running a 408, what are you guys doing to the bottom end so they live? Are just the stock caps and bolts enough for around 500 hp?

Block filling...is it necessary and how tall of a fill? to what point?

Studs/girdle???

I am not planning on turning this motor over 6000 rpm and I am not using nitrous.

This is an all forged rotating assembly I am using.

Thoughts?
