Thoughts on the 670 holley

I have a 350 hp 390 TQ 350 sbc that was dynoed with an EDDY carb, was a mess right out of the box. went through it 3-4 times and said enough, its in a box under the bench. I ordered a 670 avenger, bolted it on set the idle mixture choke etc. Never looked back. If anything, its 2 jet sizes too fat out of the box for my application. Will adjust that this summer. Best carb for thebuck. I went elec choke and vac secondaires.
