If it's an edelbrock you will need to mill off the air horn, seal up any holes, change the accelerator pump to the marine style, cut of the float and install one made of a different material than brass(can't think of what it is called)to the arm. And they do some milling underneath to pressurize the linkage shafts to keep fuel from blowing out. (I've only seen the grooves never done it). I'm sure there is more but I know that much for sureI had a buddy of mine look at it a few months ago and I swear he said it was a 600 or 650. I'm thinking it's an Edelbrock, but I don't know exactly.
Boost? All of it. Basically, whatever makes 450+. Have a diesel turbo off an 05 Cummins. It should make 450 to the tires even through this stock 351. And honestly, if it makes less then it makes less. I'm happy with whatever it can make, so long as it runs well and doesn't try to blow up on me every pass.
