I'm running a stock Autolite 2150. I think it's rated for 300 CFM, but I can't swear to that.
I'm just trying to get the thing tuned up in stock trim as well as I can for now, so whatever size power valve this thing had from the factory will work for me. Serious engine mods will come later. I'm planning on a 600 CFm 4-bbl, a good roller cam, and maybe some aussie heads depending on my mood and budget, but all that will come after I get the car painted.
