Q:i have an optamizer 600cfm carb and i wanted to change the jets to make it a 750cfm and summit told me that i couldnt do it because the air flow would not be right and it would not work.
A:Yes, by purchasing a 750-cfm main body, you can upgrade a 600 or 650 double-pumper to a 750 cfm. However the project is a bit complicated and I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed.
