lightweight motor?

Thinking about building a 383 and what would be the benefits?Like a lighter crankshaft,underdrive pulley,flywheel and smaller converter.All of the will be in a 3600lb trans am,automatic 4l60e pb,410 rear.This car will be mostly 1/8 mile races.

leave the crank, get lighter rods, pistons and valvetrain. these motors can already rev extremely well in stock trim

for the money you will spend i don't think the gains will be worth it.if it was an all out deal spinning past 7500rpm or so that would be different.you already have the gears and converter to help it rev.just get an underdrive pulley and be done with it.
