"It would appear that Edelbroc
"It would appear that Edelbrock has both marine and auto carbs but I don't know where you would stand if you did a "self mod" and then had an incident. I would imagine your insurance might become a "sticky wicket".
From Edelbrock:
For use in marine applications, these Edelbrock carbs comply with U.S. Coast Guard safety standards. Cast surfaces are iridited with Teflon-coated shafts and pump arm for maximum protection. Other features include modified bowl venting, specially designed throttle shafts, accelerator pump seal, 3/8" inverted flare fuel inlet fitting, tube in airhorn for fuel pump vent, 5-1/8" flame arrestor flange, universal throttle lever and revised secondaries for improved transient performance. Note: These carbs have no vacuum ports and are not for auto use. Use our Carb Stud Kits #8008 or #8024 if needed.
However, even if you made all these changes, it would still not be CG approved. In the unlikely event there is a fire, consider the liability issues. Buying a "marine" carb is very cheap insurance.
