Ok I have an 80 k10 350 motor that was rwbuilt over 5 year ago. Most likely 10yr. Owner before me said he rebuild it out a mild cam in and bored it .30 over I believe. No paperwork but doing a compression test they were all at 145-150. So would a holly 650cfm work or would an 600cfm work? I think 700 or more would just be to big and to start to get over fueled.
