That 78 Magnum is a pig. Ditch the 360 and blueprint you up a nice stone stock 375 HP 440. No more needed.

For a driver I'd be motor shopping at the u-pull it before building a 440. A 44re behind a 5.2 or a 5.9 would be worlds ahead of a 440 if it's gonna be driven day in/out and the driving part is primary to power and other concerns.

Ultimately wat I am looking for is power under the curve and a nice fat powerband. Now I learned years ago that horsepower is for race cars torque is what is what rules the street. Horsepower, after all, is just a mathematical derivative of torque.

And so then you'd know that to increase torque, you will be increasing horsepower. If you are keeping HP static or losing it you will not be increasing torque. This is something people often lose sight of, they want to improve what they have but do not make beneficial changes. Chrysler made 245hp with <8.4:1 compression- why do you need more to achieve it from the same engine? Planning on making over 245hp, why use a cam smaller than Chrysler did to make less?
