I am swapping a manual into my auto 305 TBI firebird, and I have every part I need except for the flywheel. I can get a stock flywheel at a junkyard for 20$, or I can get a 16 pound flywheel from GM Performance Pars for 200$. I was wondering if there is a noticable difference in any aspect (noise, shackinyess, performance,...).

any info on the subject would be nice
