Made 700/700 at 5500. We shut it off there because we didn't want to blow the bottom end out of the stock block. Torque curve was flat and power was headed to the moon when we shut it off.
Is that your preferred limit for power on a stock block?
Reason I ask is I'm thinking about a cam swap in the future, my engine makes real close to 700
With 240s and a sorta small solid flat tappet cam.
Just wondering if 725-730 is something to worry about with a studded 73 400 block
