I have a 1979 F150 Supercab with a 351m and C6 tranny. I'm wanting to increase the CFM rate for my 2150 carb. but I don't know how to do this. Is it possible? I've heard it can be done but I haven't found any instructions on the web. The carb. has 1.21 stamped on the side.
The easiest way (not taking into account emissions, assorted vacum lines, computer controls and such) is to find a 2100 with the 1.33 stamp on the left side, it has a 424 cfm rating compared to the 1.21s 351 cfm rating. Holley makes a non-emissions 500 cfm 2v carb.
