I'm trying to make a decision on this also. I have a 500" low deck with 440-1 heads and Indy 1.6 rockers.
I want to step up to Harland Sharp rockers but I'm debating on switching to 1.5's since the new cam is 706/661 lift with 1.5's. I'm worried 1.6's will give me too much lift for a street strip motor.
