i have been told that the 3.2L will give you alot of low end power but no torque or upend power

smaller cam = valves open less = higher velocity through chamber into cylinder(greater air flow) for LOW RPM = good torque...not good for anything past 4000 rpm

the 4 litre one, the smaller one is only good if your towing heavy loads.

spend 150-200 buks and get your stock one regrinded to any spec you want! bang for ya buck ;)

You can't spend $150-200 to get one grinded to any spec you want ... If you pay that to have one grinded, then it already has masters of it made.
