I`m also reading and dreaming. But here is the question I ask: How do you take a stock block that is considered "marginal" at 600HP,and stuff a 4.25 crank in it and bump power up to 700+ and still sleep at night? I understand all the terms like----- good assembly practices,"good" machine work,quality parts etc....... But isn`t this the same group of people{myself included} that consider a stock block a "bomb"?
Besides filling the block,what are you planning to do ? And how long do you expect one of these to live?

Torque peak should be around 5200 rpm with power peak around 6200 rpm.



Keep the RPMs under 6500 and take a sleeping pill?
