I dont think theyre heavier than F-bodies, arent F-bodies anywhere from 3500-3700 pounds? Z32’s are less than 3200 I believe.
Edit: Just checked the Non-turbo 2 seater is less than 3200 pounds, but all the other trim levels of the Z32 are over 3400. So if someone found a clean 2 seat nonturbo thatd actually be a pretty badass donor car for an LSx swap.
