The cylinder dimensions are far more important than the total displacement.
All wedge chambers are pretty similar regardless of brand or size: Chrysler A & B, Olds early and late, Buick 400/455, SBC, Cadillac, FE, Windsor... it's a long list.
Dual pattern cams are useful to correct flow differences larger than the traditional 100/75 split (although there are other fine-tuning purposes), but it's not closely linked to chamber design.
