I have always liked the Edelbrocks I think the Spoeed masters are copies of. Is there used Edelbrocks around or do they wear out where they are unusable. I never see them used anywhere.
IMO, I think the thing is the Edelbrock head is a pretty good head for what it’s designed for and of course does really well when ported. This we all pretty much know.
With that in mind, they’re also pretty easy to repair. There’s no much sense in getting rid of them for the most part if you’re not moving up the scale on head flow and performance. So it’s better to keep them and repair them most of the time.
This is the reason in my head you don’t see them often up for sale.
