Heart surgery and eye implants,and still working on your "Bolt"! Yo "Da Man",Chipmunk!! Jerry is right-on with his advice. I have the "stock" head,(steam ports,stock cam),on my 261. When I add/change coolant,I need to "burp" the system,to get rid of the air pockets. The first time I added coolant,I wasn't aware of that fact,and lost almost 2 gallons of antifreeze,when I,(luckily),over-heated in front of a mechanic friend's house. He started it up,and at high idle,added water,until the engine finally got down to operating range,(about dead center). It took about 10 minutes,but it seemed like a lot longer,hearing that thermostat bang open and shut,from the difference in water temp. I drove it back to the farm,and the gauge dropped down to 1/4,on straight water,on a 95 degree day!! Now I know!! I have Fentons on my 261,but I use the stock intake. I'm not sure,but I'd think you'd be better off trying to set your vacuum/timing with the dual carb set-up,especially since you have a cam. Otherwise,you'll be doing it twice. I may be wrong,but with a "racing" cam,the single carb. will act a lot different than a dual set-up would?? Hope this helps! B.T.W... GET WELL SOON!!
