I went out to look for theses salt and pepper shakers, and found nothing. I have a converted 4cyl and I didn't swap the motor. My car idles around 750 with a mild cam, but idles crappy when its not warm. O2 sensors maybe? Also I have the battery mounted in the back and I only have one 4 gauge ground running to the battery (bolted to the intake manifold). Is that enough?
