Anyone done a strong 400 build ?

685 HP at 5800 661 tq at 4800
470 nothing fancy. 240 tf's , smallish solid flat tappet cam, home welded and ported tunnel ram with 2-850's
Alot of extra work making sure it was as good as I could make it.
Will easily make over 700 HP with a optimized solid roller, But like Andy said 700 is pushing it with a stock block.
I'm hoping to get some passes with this sometime this season

That looks badass just sitting there. What were the cam specs again?
