aluminum vs steel flywheel for stroker

A alluminum flywheel will be more resposive on acceleration in gear. But a heavy flywheel will keep the motor spinning on shifts and on pulling out . It actually makes the rotating assembly harder to stop because it stores the torque already made to start it spinning . A drag car heavy fly wheel, a oval or road course car light flywheel , A sprint car none if rules permit.

I would always replace the 70 and up BB flywheels with 69 and early for the street They were bigger in diameter and heavier. Instead of the 70 up cars just chirping the tires they would keep-em spinning like the 69 and back.
