Hey guys I was wondering if you had any recommendations on jet sizes to use for my 250. I have a comp cams 260H .040 over pistons Port and polished head with bigger valves, Offey intake and headers. Its a Carb of one of my V8's (350 I think). Anyway I know it probably doesnt need 600 cfm and I would like it to get good fuel mileage as well. Any help?
