My Holley 750DP is circa 1970, and it still works great! To be fair, it hasn't been in service for every one of those years, but maybe half? I regasketed it a couple of times, tho.

Edelbrok are good out of the box but I don't think they rebuild as well as Holley but I've
Always had good luck with them new.
