Hello, check with Chris Straub cams- great guy and super knowledgeable. He has a killer Hyd. Roller for BBC, I have one in a .30 over 454 build but haven't put in car yet.
Jose has the same cam in hid '67 Camaro L78 car- there's a thread on here with video of car running. It's wicked sounding and has good vacuum. 229 intake duration makes it work well on street, especially with auto trans. I think Jose's username is JBtech on here.
the cam has gross duration of288/300 from memory. Chris will know the exact cam I'm talking about- I have cam card at home but won't be home for a few days.
Hope that helps!
Jerry
