hi, I read all these comments on light versus heavy wheels. I run a a stocker 340 duster with a mcloed alum flywheel and a soft loc clutch. I have ran the mcloed l/w steel wheel, (18#) also. the difference from a heavy (30# )wheel to 11# alum wheel is .2 tenths and 2 mph faster. the heavy wheel slowed the engine down badly. I have ran l w flywheels on all my stick cars. first was a 265 chev, and 4.56 gears, could launch at 5500 rpm, and not spin the tires. most guys ran a 30# wheel, and spun tires, I won. true, you have to leave at higher rpm, with alum wheel, you're making more power at higher rpm, so the car will go faster. the reason the factories used heavy wheels was so the average idiot could drive with out ruining the clutch. they had to make it idiot proof. less warranty problems. the faster a engine can rpm, faster it will run, simple ,
