are you sure about that??

 

well I guess it all depends on which model you have during which year and what month of that year it was made. I would like to have a list of all the options available on f100 f150 f250 f350 during the years 1973-1979, I know it would be a huge list.

 

I have seen this before on the 1/2 ton but not very many. Believe special/heavy 1/2 ton truck 4wd. On the comments on comparing 2 barrel carb making 650 hrspwer and comparing to ford 2 barrels this is a joke. barry grant used to make a 750cfm 2 barrel carb. Not up to date on nascar 2 barrels but those are some serious carbs. They run a little more compression and way better heads and intakes. Ford truck carbs are not serious pieces. Need to measure your butterflys and which carb the smaller cfm or the bigger cfm 2 barrel carb. catch you guys later.
