slant cam guessing game...428 lift?

I had a spark plug that I bent the electrode out on but I can find it, but I think 10 bucks for an adjustable stop is worth my time. Too bad auto zone didn't stick it. They had the best price beating ebay. I'm going to make a bar that my dial indicator will mount to that goes over the entire lifter bank so all I'll have to do is loosen, swing up and slide it over to the next position. Also a clamp on pad that will go on the pushrod that will give me a point to measure it's lift as the swing of the rocker tip moves it off the dial indicator probe if you measure off the rocker. I'll bolt bar on using valve cover holes. Pics to follow. All this to ID a cam, you bet! Plus it'll be fun making it on a Sunday afternoon.
