If you are talking about the link RodStRace posted the article says it's courtesy of Street Rod Action magazine, no longer around.

I know at one time I had the magazine in my collection, but the last time I remember seeing that it was last millennia, probably when it was the current issue.

I may even still have it but the article linked is the extent of what was in the magazine.

If you are looking for the V8 swap kit talked about in the article, well it's not really available any more. I don't think Mr. Street Rod is in business anymore. Nor is PlyDo which was the hot rod place for older Mopars.

Butch's lists a kit though
