In response to technitom
I made a pretty accurate timing tape using MS Excel... formatting the row height at 8.75 (excel only lets you change in increments of .25, even though you can type in a height of 8.73, it defaults back to 8.75) makes my timing tape come out 1 degree too big over 60 degrees of total timing....
In other words my 30 degree mark on the tape is actually 30.5 degrees. when total advanced timing is somewhere between 32 and 36 degrees for most small blocks, I dont think half of a degree is going to make that much of a difference in the grand scheme of things... if anyone wants this file lemme know...
formula used: 6.75"(DIA)converts to 171.45mm X 3.14159265358979(PI)=538.62606 divided by 360(degrees)=1.496mm per degree of timing.
the tape starts at 12 degrees ATDC to 60 degrees BTDC with markings every degree, every 2 degrees, and every 10 degrees. labeled in 10 degree increments starting 10 ATDC to 40 BTDC...
I printed out and hand measured half a dozen or so versions until I could get to as accurate as MS excel would let me...
Words are a lot like toothpaste... Once its out of the tube,
there's no getting it back in...
