Then you are one lucky guy 68cjmustang!
Hey, I've no dog in this hunt but across a wide spectrum of websites I follow, Ford, Chevy, Dodge, general magazine and engine builder sites, there is almost universal consensus:
ProComp stuff is junk!
And that's as mild as a statement as I can make as I'm grateful to the many pro engine builders across that Web spectrum who advise to stay away from ALL their products. Just use the search engine on any Ford or car enthusiast website (ProComp, junk) and you'll be amazed at all the horror stories.
