I was running a 350cfm holly and it worked great. $100 if a fairly good price. My truck is not a DD so I took the choke off and it took a few minutes to warm up but ran fine after that.

No tuning, I used stock jets. 15 deg btdc, make sure all ports are plugged and let her rip.

you may need a throttle return spring. The throw on the stock carb was a little different then the Holly. I made my return spring from one I found at the hardware store and some zip ties.
