Cam sensor Timing


Dec 14, 2005
question regarding setting the timing...

I'm building my first buick engine (actually my first engine ever), and I am completly confused at how to set the cam sensor at the 25 degrees ATDC. I know about the caspers tool, however if I can do it without any special tools it would be great... So if anyone can give detailed instructions on setting the initial timing, please let me know. I'm so close to starting my motor, I can almost smell the exhaust!!
Thanks in advance!
