Four ribs? Should be eight, for 8 cyl.

Love My scope but it is a re-learning experience every time I use it. Very seldom but I have the manual to blow the cobwebs off the grey matter. It has led me to a cam going flat many moons ago. Primary and secondary patterns, Relative compression test, burn time, vaccum wave forms Yada Yada. I need to use it more but not today I need a BEER.

There are 8, and I ended up checking 7 of the 8 ribs/lobes. Dead on. Also checked the vacuum canister and it holds vacuum. Next up: Checking for intake leaks. I also ordered a set of 8.5mm wires.
