Boosted slant?
You say that you're running an intercooler, so can I assume you are running blow thru and not draw thru? I'm planning at least initially to get it running on a 318 BBD carb so I was looking to start out with draw thru. 5-7 psi was about what I had in mind. Are you running a stock cam? I had mine reground, Oregon cams took care of what I was after, but I hope the cam I picked will be alright with boost. I know it has no overlap, otherwise it's what would have been considered an "rv cam" back in the 80s-90s, you don't hear cams called that anymore. It definitely isn't anything radical.
I want to run the BBD that I have if possible because it's an nos carb that I bought a couple of years ago, and only has a couple of hours on it since I took it out of the box. Genuine NOS, not chinesium.
