Finally got my HR 4/7 swap cam from bullet. This project has progressed into a full rebuild,, not what I was expecting. Going to internal balance,, they said they had to add 15 grams to the back of the crank. Now that they have the cam they can move along with it. Thanks to Paul and Jay for parts and advice. I’ve been using nothing but rhoads regular and then the vmax since the 90’s on my street cars. Hopefully my off idle punch and brake vacuum will be acceptable without the rhoads. Using the evolutions.
