Re: carburetor help

rectangle port is a high rpm application. you will be able to use all the carb you can get, Usually I wouldnt say that, because most people tend to use too much carb. I dont know what that cam is, but I'd guess with a torker and those heads you'll be able to use all of an 850 and then some. Might not be a great combination for street driving.
