I have good Holley 850dp (manual sec). It was dialed in and running great on my 460 (healthy stock, paul kane built motor for me).. My floor rotted in my boat, so I pulled motor to work on it.. we'll that was two years ago, it's been in my garage the whole time.. let me know, I'll send you pic.. or I'm in Lakewood if you want to check it out..
