Ok bro first thing you need to do is get that regulator on. Otherwise you're gonna run rich no matter what. It will run better after that but you *should* also change out your intake to have it run correctly for the engine. There are people who will buy your victor junior intake as well, by the way. Put it on Kijiji and craiglist.85montanezSS said:Well 454Musle its using up a lot of gas but my brother in law found out there isn't a fuel regulator so its dump fuel you can smell it through the exhaust fumes and see the gas needle go down very fast so the fuel pressure gauge is reading 12lbs of pressure so I ordered a regulator for it but the main thing is I have a holley 600 and a victor Jr intake and they told me to change the carb cause I won't get great mileage with it and the intake isn't suitable for my car cause I'm not running high rpm so they said get a dual plane intake with a Quadrajet so that's where I'm at.
Next, if I were you, I'd surely get the carburtor changed. Here is what you need: http://cgi.ebay.com/ebaymotors/QuadraJe ... 45f74b28ca
And also thats some good info from art by the way.
