As most of you know these big numbers out of "dyno queens" don't really interest me because of all the tricks and costs making them one hit wonders, BUT I love seeing what the Victor heads can produce. Hopeully a set will be on my R3 block (or Ritter block) in stroker form so I can keep the RPM down and make a nice BUDGET long lasting bracket race engine. I would love to know what that block sonic checks at being a 4.100 bore.
