I am using two B's on my 216 one ton, I get about 16 mpg on my 35 mile daily commute, which is what I got before I put two on. Except it looks cooler, and goes faster. It has the 5.14 rear end in it.
I love that air-cleaner, where did you get it?
From reading California Bill, and my own limited experience working on my truck and driving it:
Are your carbs matched?
Are they in Syc?
Do the choke(s) come all the way off?
Are you using a choke in both?
Are the float levels right on?
Is your timing advanced enough?- I'm about 12 degrees ahead now, and not done...
Is your valve lash set right? (hot) Loose enough is important
Are your plugs clean and gapped right?
What do your plugs look like, after a pass? -like a 1/4 mile at or near full load in high, shut off ign as you clutch, no idle.
What's your vacuum at idle?
What's your vacuum while driving around?
Is the vacuum advance working right? Very important.
Are your points set right?- I see you are running electric ignition, I don't know about that.
What's your gearing. A taller rear end doesn't always mean better MPG.
More cam means less low end, which can lead to worse mileage.
Oh boy, will someone ever burn on me for the last two!!!!
I'm sure someone will chime in with more knowledge. Did you read the multiple rochester b tuning info on carbkings website? Its good info.
Do you have a copy of California Bill?
