torque
Ok i have a 5.2 Magnum and i'm wanting more low end torque out of the motor. It already has exhaust and intake and has been hypertech programmed. What is the way to get the most bang for the buck?

RE: torque
Then what you need is more displacement, higher compression ratio, or forced induction. You can run a lumpier cam but that'll most likely move your power band up in the RPMs. If you went with a lower RPM range cam it'll hurt your upper end horsepower.

wrong. Harland Sharp 1.7 rocker arms and a 48mm F&B throttle body will show horsepower and torque gains throughout the whole RPM range. These 2 mods on a 3.9 have shown up to 30 horsepower and similar torque numbers. A 5.2 is the same motor as a 3.9 except bigger, so expect to see the same types of gains.

Got any dyno graphs before/after to back that up? I don't doubt that both hp and torque are added, but logic says it would shift the numbers up in the RPMs.
