My friend used to a have a 69 Firebird w/a 400 hood w/tach.
I helped him take off his hood a few times & could not believe just how damm heavy the hood was as compared to my standard 69 Camaro hood.
Anyways, just a thought, I know how much heavier the 69 Firebird is compared to the 69 Camaro & I always try to find a way to lighten up my Camaro because lets face it we are at a disadvantage as compared to the V-8's LS1,2,3, etc.
