he he he, yeah i agree with you guver... i think we are pretty much thinking on the same track here. and i see what you are saying about IF you only change one thing.

by the way.... for you people that don't get the general statement of !QUOT!more weight=more torque!QUOT! think of the statement !QUOT!an object in motion tends to stay in motion unless acted upon by an equal or opposite force!QUOT!

this means that the heavier the item, the harder it is to stop (think bowling ball vs. feather). so if you have a nice heavy piston coming down, the car is going to have a harder time resisting movement of that motion, then it would if it were a nice light weight piston.

now the plus side of a light weight piston is 1 you can rev it higher (again assuming nothing else has changed) 2 you will see an increase in H.P. and 3 the throttle response will be faster.

there is a lot more to engine weight then just the piston, there is the weight of the rods, crank, flywheel, anything spinning...

anyways.... enough about that, i am sure most of you know all of that already.
