I need a little help. I am have been building a blown bbc motor. I have a couple of questions on the spark and injection setup. Here are the specs on the engine, bbc 540, 11.5-1, 14/71, bird hat w/port setup and msd mag. The motor hasn't been assembled completely yet. What is the pully ratio, timing, spark plug and gap that I should start with. I am a little new to this and i nedd a base line to start from. Thanks for any input!
