Isnt that what getting opinions on here are is hear-says? lol
All my experience is with edelbrocks and have never had a issue.
No expirience with holley but if there is a bunch of people having the same issues or saying the same things its kinda hard to ignore it. Im sure there are plenty of holleys that get bolted up and run fine but i dont think i have ever heard of a edelbrock not working 100% out of the box unless there was a factory defect.
