I just got my new 350 HO crate in. I used my old quadrajet carb and put an electric choke conversion on it, removing the old stove pipe choke. Now when I start it up it seems to take a while to engage the choke. Then after it warms up the high rev won't disengage. I ran the power wire for the choke to the alternator hot wire. Could that be a problem? I tried adjusting it and it got slightly better but not great. Also it seems doggier than it should considering I more than doubled the power of my blazer. Also my last question. Do they make 600 cfm jets for a quadrajet? If so where can you get them? They recommend a 600 cfm carb for this engine but I wanted my quadrajet as it ran awesome on my old engine, but I believe it's a 650??
