Straight 8's hmmm
Not myu specialty for sure but always fascinating.
Approx I have
720 Buick 263 (GUESSING the 248 and 233 are same block ~same wt?)
815 Buick 320 (about twice the Nova 6)

614 Olds 240 and 257 i8
655 pontiac 268 (GUESSING 223-232-249 same block ~same wt?)
752 Packard 359 (GUESSING 288-327 same block ~same wt?)

Pretty sparse. Heavy iron!
