I saw this Edelbrock CH-28 intake on eBay that looks to have the Vanke modification that they do with the Dual Quad stock Hemi intake manifolds done to it...
eBay item number:
322668731375
It looks like it has never been bolted on an engine... I am curious if anyone has done anything like this to the CH-28 intake and if it made a lot of improvement? or..made it worse?
