I have a 90 yj with 258ci in it. Has Clifford intake and headers and no cat. Wanna change from 4bbl to a 2bbl, should I just go with bigger cfm?
agreed..the front 2 barrels on a 4 barrel will normally get a lot better mileage than the larger barrels on a 2 barrelGo to Holley.com and check into their "carburetor selector guide". Answer a few questions honestly and they will provide you great choices. Why would you buy that intake system and not go with a small four barrel? You would probably get much better gas mileage because you would be running on your primaries most of the time, except when you were on the highway, or punching it.
