does anyone know if it is possible, or has anyone converted a dohc engine fitted to later sierra models and others, to run carbs. the only reason i would like to know is the plenum sits very close to the bonnet not allowing a strut brace to be fitted. is there another way to run injection on them without the large plenum, ie a different plenum with less height. could just not fit brace but want to explore all options first.

DOHC converted to run a carb?

really?

yes ford put them in sierras and sold shitloads of them

they are non-injected sierras without holes in the head and port shapes changed as they had no injectors

easy peasy!

p.s normally find these in low spec estates for some reason?!

a carb hasnt nearly even the same power as an injection set up i would advise getting an engineer to muck up a strut brace to go front and back of the engine this will be a much simpler cheaper option imo

are you saying there was 2 different types of injection engines?
an early one and a later one?

yes, AND a carb engine from Ford.

didnt have holes in the head or ports for injectors
