I've got an open element K&N filter, Edelbroke 600 w/electric choke, Performer intake and Vortec heads, etc. Runs great in warm weather but completely sucks in cold weather. Is there anything I can do to help it out without switching any major components. My mechanic buddy said something about it not having any "crossover" and that hurts the cold weather driveability. I'm kind of a retard when it comes to this. What is he talking about? Something with the intake or heads I think. What about using a snorkel style air cleaner assembly with that air tube thing that goes from above the exhaust manifold into the air cleaner opening. I'm not explaining this very well but I hope you all understand. Thanks.
