The W5, IMO, is that last step up us regular guys can take. The W7,8,9 is a bit much for many regular people to handle and properly equips and match parts to.

The W5 had problems with the early castings which gave them a bad rep they never shook off. Coupled with no intake that fit them in the early days, poor public relations, poor advertisments and there in general pricey expense for the time, it is all that was needed to create a poor selling product they will not stand by.

The death nail for the head is the Edelbrock RPM head. While it does not perform as well, it is at nearly every race/hot rod shop ready to purchase. They just need a quick looking at, correct any issues and your ready to go.

A damn shame MoPar never went this route or advertise if they did.

I have a bare set of W5's and will let all know how it goes when I get there.
(It'll be awhile.)
