Before anything, I want to stress that I'm not looking for as much horsepower as possible. I'm just curious what I will be making.
86 K20, 350, th400, NP208

Engine was rebuilt 2 years ago and has less than 2000 miles since. Factory heads. I'm swapping cams to Summit Racing K1102 cam/lifter kit, Edelbrock performer dual plane intake, edelbrock 1406 600CFM carb, Flowtech Long tube headers with dual 2.5 inch exhaust and Flowmaster 40 series mufflers.

Any idea roughly how much power it will make? Again, I know there are better combos for more power. I'm not looking for that right now. The parts are already on my workbench, just waiting for a dry day to install.

I’d venture to guess around 240 without the cam.

That may be generous though. I don’t know the exact figure a 350 made that year, but I doubt you bolted on more than 40 hp with the stock heads.

edit: I revised my estimate, but I’m probably inaccurate anyhow. Smarter folks will chime in.

That's about what I was hoping to hear.
