I was planning on throwing a set of rods,pistons, and pi heads on my npi car to take a little more boost from my s trim. What is the limit of the stock cast crank in my 97 4.6?

Im running stock crank with H beams and manley pistons , from what I have heard anything over 600 rwhp is asking for trouble , but under that you should be fine
6800 rpm.... 640 rear wheel. No problems here on stock cast crank. It's cheaper, and they're just as strong up to a certain point. You'll rarely hear of someone breaking a crank in a street/strip car. Road racing is a different animal.
