Edelbrocks new owners seem to have a different business plan. They have gone to one plant in California manufacturing parts. Then when there are enough orders, they make them, send them out. There is now very little "stock" on the shelves. Some parts have not been made for over 2 years, and because, the backlog is not big enough, they have not been produced. Considering the cost of aluminum has about doubled in the last 20 months, this is how they run.
This works for edelbrock, but try ordering for a engine build someone is doing. No way to predict when the parts will be manufactured. Case in point, was ordering a pair of heads for a 460. They were on order for 11 months, edelbrock finally did a run at the end of 2021. Now they are backlogged, again. So one waits again, probably another year , maybe longer.
