Admittedly off subject is told not to be LOL but I'm still completely trying to wrap my head around they had that flows from 3500 to 7500... They stall converter that probably is at least 3500... And how you're the only one on earth or at least on this form who isn't questioned about their combination of the vehicle that it's going into. Gears, cam, weight, expectations... 450 to 500 horsepower to do what? Torque???? ...
Because I didn't ask how to "build" a 450 HP 440, nor did I ask "how to make my truck run XX.XX ET with a 440, my question was straight forward. "These 3 head competitors, which is the best for the money. Quality, Performance for the $$."
