Default Need some carb help

I have a 64 pontiac catalina with a 455 i recently changed the edelbrock 600 to a holley 670 vac sec. and for the life of me i can't get this thing dialed in,so im wondering if there is someone in the fortworth area that could stop by and help me out. I'm willing to pay someone to get this thing running right so i can get her back on the street. i'm in the fortworth area off 35 near cabelas let me know if you can help out thanks.

I have a 455 in my 65 grand prix and a box stock edelbrock worked best.

I am not a carb wiz and probably left some HP on the table but it runs great
