Carter bbd

rochester 2GC small bore same stud pattern but no idea how tall...
Stromberg WWS not WW is supposed to be same
no idea how tall

other options
2-4 BBl adapter plate
4 BBL to 2 X dcoe with 2x weber 45DCOE running say 40 mm venturies the number 5 aux venturis
aussies used them on small block v8 and went 24 hour enduro racing
Redline 12-3144 Twin DCOE Weber to 4 Barrel Holley Carburettor Adaptor | eBay
don't be tempted to compare CFM it doesn't work for weber carbs.


stacked adapters will probably be lower than carter BBD + 1.5 or 2 inch deep pie tin filter

nikki carb? 2 bbl from japan no idea on studs buit once your remove all all usual VW bug adapter (the only people who ever used them) might make for a decent 2bbl if you can find jets

36x36 weber DGAS DGES used on 3-3.5 litre ford v6s wrong stud pattern but may work out lower profile

if you go weber everything you learned about holleys is relevant but applied in a totally different way.

id be tempted to go 2bbl low profile throttle body with remote filter and drill the inlet manifold for injectors
