I had some time to compleete my tool to messure all engine timings. In the past I did find out that just some light was needed to determ the opening and closing moments of the crankshaft and ports in an easy way

What I was using for a while:





Using a piston stopper to fix the moment of opening/closing



And the digital angle meter on the crankshaft:




The main problem was I did not had a good stand to mount the engine and the lights. Then I came up to this project:

A PCB with 7 very bright LED's in a stand and a seperate LED



A 3 position switch can set to off, the one LED or the 7 LED's





When mounting the engine with angle meter it looks like this:



Enough light to find the right timings (the light is also clear at the intake ports):



As seen from the side:



It is a direct fit for all rear exhaust small and bigblocks, it has an very quick and easy mount and in a few minutes you have all the timings without much handeling.

Now it does need a finishing touch like a good paintjob and 3 rubber feet for a steady placement.
