I have the LT4 hotcam in my 350 TPI I was running 1.6 rockers and I changed to 1.5 whats the lift on the car now? It was .525/.525 with 1.6 rockers I thought you divided .525 by 1.6 then muplity that by 1.5 but I get .480 is that correct? Or am I doning something wrong. What's the formula for going done on lift numbers? I was figuring about .500/.500 lift with 1.5's I did not think it would go down that far. Thanks, Jason

You procedure is right, but you somehow got the wrong answer. Punch it in the calculator again.
