I've had good luck with Eddy carbs but find the 800 i have now is being a bear to get the right fuel mix through out the RPM range. I'm thinking of bitting my tounge and going with an 800 DP. But i will get a new one not one somebody has been messing with. If i do go with the holley any jet recomendations? 68 HP440 i asume is stock comp as i haven't pulled the heads. Heads apear to be stock as i see no obvious porting. Voodoo 604 cam. 727 w/2800to 3200 stall 3;55 gears B Body Eddy perfomer intake. MP electronic ignition with chrome box. Manifolds with 2.5 pipes hemi style mufflers
