Getting ready to order my new motor. 540ci, dart block, all forged rotating assembly,9.5:1 compression. Edelbrock performer RPM heads(rectangular port). I am anticipating 650 horsepower, and 700 lbs of torque. Considering the less than 1.3 horsepower per cubic inch, this motor should be stout and take a beating too. I haven't selected a cam yet, but im curious to see what everyone would recommend for a carb. Also what do you think about the cam. Its going into an 18 foot Brendella bubble deck, Jacuzzi Jet, I'll be boating mostly on the Colorado river.
