I have a 225 with a 390 4bbl, there is a 5.5 power valve, 51 main jets, an A904, with 3.23 peg and a MP .438 lift cam. To better dial in my secondaries I bought the Holley 34-6 kit (secondary metering plate, blocked off Power valve), what size jets do you think I should start off with to better dial in the motor. Im not complaining about my mileage I get 14 city and 18 freeway, I just want more (c: Pyper70@aol.com |

The one I have usually likes the secondaries about 3 steps richer than the primaries. Dennis slantzilla@excite.com |
