I have had a new throttle body on my list of parts to purchase for a long time. I was under the impression that BBK was selling their throttle bodies to Edelbrock since hte Edelbrock parts had both logos on them, but I noticed that the Edelbrock throttle bodies recently took a huge leap in price. In the past they were about $40 more than BBK, but now they've shot up to $300 when BBK parts still come in around $200. Is there any real difference bewteen the two? Did Edelbrock actually change something or make a better part which justifies the price increase?
