unhappy with eddy need a change lol

just my 2 cents, what size is your motor?? i am thinking 318?? I would get headers, performer manifold and rebuild the 600, I had a eddy 625cfm on my 360 for 25 years, I liked it ( I have the 650 Thunder Series AVS now) and some people have said the summit carbs are not too good, don't know but thats what i read on here.
3.55's would be good too, but then your adding $$$
