Im curious to know if anyone has changed over like me and has had any of the problems im having.

One is i cant seem to get the car any richer then 12.3 AFR. I would like to get down to 11.8-12.0 at the leanest . I have #8 AN line feeding all the way to the bowls. carb has 90's in the front and 107 jets in the back . its a dead headed holley HP 125 pump . This motor is in the ball park of 650-670hp . Anyone have any ideas on whether or not its the pump not having enough ability or maybe the #8 is to small? I know that the fittings for the #8 measure around .330 thou ID. So im thinking having a bunch of these in the line that measures .490 id could be a potential choke point ?

Second problem is: It bogs on a quick stomp. Doesn't matter if its from a dead stop or from sec gear cursing down the road it will happen . i have a .045 squirter in the front with a 50cc pump . Back i have .050 squirter with a 50cc pump . Both have the hollow screw. The old setup on 91 octane had a .035 in the front and a .045 in the back. It worked great. It was all business ... So im not sure whats going with the change ..

Other then that it screems. Im super happy with it.

If anyone can help id really appreaciate it..

Thanks...

Did u do anything else to the carb? Air bleeds etc? There is more to it then just jetting
