Hey everyone, I'm new to the forums and am currently building a 468 to go in my 1970 Chevelle. This vehicle will be used street (40%) and strip (60%). I want to run a solid roller cam and it has been suggested by several cam companies that I run a cam in the area of low to mid .700" lift. My engine builder says that he believes that high lift roller cams like that don't fare to well on the street. He says that with the fast ramp rates, it may stretch valves over time. I have told every person at the big cam companies what the car will be used for. Do you guys think this might be a problem? Have you heard of this? I am just worried about durability. I don't want to have to tear this motor down every month to check valve length's....

Advice please!
