Well that's not what I'm saying at all. I've just read that people have a horrid time getting this 500cfm carbs to run correctly on street cars. Everywhere I've read has said that these were made for circle track racing where the cars are almost always at full throttle.
Another thing I was thinking is that it was simply too much carb for the engine. I mean the stock monojet was like a 190cfm carb. It just seems to be a huge jump without doing the valvetrain.
