Let me throw out another question. I'm in central Iowa. I've been told by a few people that there is a guy around Omaha that specializes in Pontiac tri powers. But no one remembers his name or how to get ahold of him. First, does anyone know this person? Second, looking for opinions on converting to the tri power set up. I'm inclined to stay with the 4 bbl but could be convinced to switch, for a reasonable price.
