Just bought a 80 F350 for $ 600.00.
The carb is a motorcraft needs a rebuild and is leaking a little .
It has the duraspark II system (not sure)
its a 351 . whats the best two BBl to put on it for mild Hp gain and better towing /heavy loads.

You would probably see the best gains with a Holley 2300 series 500cfm 2BBL. They also make a 350 cfm one, but that wouldn't be to much of a performance gain. I believe the stock cfm of your truck is around 300.
To find out the cfm rating for your carb, look for one of the following numbers on the float bowl, the cfm rating directly across is the one for your carb. Thank you to chas1234 for this info.
Number = CFM
.98 = 190
1.01 = 240
1.02 = 245
1.08 = 287
1.14 = 300
1.21 = 351
1.23 = 356
1.33 = 424
