Here's 3 tuning articles from David Vizard...famous for racing a 175hp (at the wheels) Avenger beating all the twin cams!
Includes a simple 14hp power increase from modifying the twin Stromberg carbs and their inlet to exhaust manifold mounts.

Awesome. Cool find. I read these years ago but gofastnews took the originals done. I have a few other article by him about Avengers.
Btw I fixed up the broken links for you.
Cool, can you e-mail those articles to me Richard and I'll pass them on to Steve, who provided these articles.
They are in some old magazines. I will find them then scan them and put them up on the forum.
Thx Rich, have added part 3 of David's article to my original post.
