That's pretty cool, I'll have to check them out. I dont have anything that is worthy of a racing only carb, but maybe some day. 1980 el camino, engine swap for a 350, 4 bolt main, 010 block, th350 trans. Just need to get a few more things bolted on the front and top off with fluids, see what it does on some pavement. Hopefully will have it on the street in a few weeks, it's my first build.
