Race carb or Street carb
I am running a Pro Systems 840 cfm street carb, double pumper ran 675bhp on my 373 SBF Yates engine at 7200rpm, apparently the carb is 10 year old and the part number indicated they were designed for the shelby corporation.
My thoughts are as my engine runs to 7000rpm and my use is street and road racing.
Is there any advantage getting a purpose built road racing carb???
This carb needs road race floats, it appears to have the modern contoured body etc and looked like a race carb.
My knowledge is limited in this field I assumed if the jets, pumps etc are ok and it flowed the right amount for my engine then all good. I read where race carbs have a different fuel curve as they operate in the 4000 rpm plus range which may be detrimental to my use of some road use, where I need a reasonable transition from take off. I don't think my engine has a great deal below 3500 -4000rpm, will find out one day when I get the project finished..
