I happend to notice a website selling a 4.6 SUV motor w/ 600 miles on it for a good price. I know it has an aluminum block and puts out 232 hp, 290 ft lbs of torque. What makes that motor have less power than the mustang? Is it all in the cams? I was possibly thinking about picking it up and sticking my stage 1 cams in it with an aftermarket intake and long tubes, but would I be loosing power? or is there some other modifications I need to do to the motor to give it more power?
