I have a 1982 F-150 4X4 with a 351W The engin has been rebuilt with a towing cam and it is bored 30 over. The normal intake manfoild has been replaced with a 4Bll intake. The problem is the truck get about 6 miles per gallon. I think that it has the worng carb. on it. (or am I just Crazy) I also having some choke problems. I NEED HELP!!!!!!!!!!!
PLEASE

I would like to know what CFM to get plus what brand would be best.

 

If you go to the Holly or Edelbrock website you can send an email to the technical department with your engine specs and they will recommend a carb. Personally i would go with a Holly truck avenger or street avenger carb because they are really simple to tune. If i had to guess i would say a 650cfm carb would be about right for your engine. I'm building a 351w right now that will put out about 500hp and 550lbft torque and i'm only using a 750cfm on it.

Do you know what carb is on it now? Maybe it just needs to be adjusted and have the choke fixed?

Jon,
I am not sure what kind of carb is on the truck. I have looked for an I.D. tag and someone has removed it. I have even look for the manufacturer like ford or carter but with no luck. I was thinking about just a strait Edelbrock 500cfm 4 bll.

Do you think that the 500 cfm will be a good choice.
