Just one thing. I gave them all the specs of my motor I built. They suggested a certain carb that weas way off. I got it put it on it didn't run right and they wouldn't take it back. There excuse was well just because your thermostat was stuck and we suggest a new water pump doesn't make it our fault. While I understand that, that is not what I asked. I gave them every detail and they fu**ed up. Obviouslly having a draw-through blower I would need the boost ref. carb.
