I have a bunch of original dyno sheets from a 288 cid small block motor that didn't quite last to 9,000 rpm.

"exhaust lash caps found missing"

It was an idea. But I don’t know if it got raced.

My Chrysler internal correspondence between Tom Hoover, Bob Torozzi, and others seemed to say it was an idea that didn’t work.

Browsing through many runs by Bob Tarozzi’s Phoenix Engineering, looks like all around 520-540 or so peak HP. BTW, SVI= Ted Sphear. DRE = Bud Elkins ported/prepped

This run had rpm “issues” it seems by the comments
