Your Question Was: Does Quick Fuel assemble custom ordered carburetors?
In particular, can the SS-680-VS and SS-780-VS carburetors be assembled with annular booster venturis?
This would make them equivalent to the Demon 1282020VE and 1402020VE carburetors which are no longer manufactured.
Other equivalents are the Summit Racing M08600VS and M08750VS, which is a line of carburetors Summit acquired from Holley long ago.
thanks for contacting Quick Fuel,
yes we could install annular boosters on those carbs. you would be looking at an additional $125 on top of the cost of whatever carb you wanted to go with.
