Help reading Timing Tab
I'm new to small block Chevy's. '63 with a 283/Powerglide, all stock as far as I can tell.
I've only ever timed VW engines with degrees on the harmonic balancer.
The timing tab is perplexing to me, and I can't find more specifics using forum search.
The tab looks to have a "O" and "A" and about 16 degrees of timing? Is the O a zero, indicating TDC? If so, where do I my initial timing to be on a stock motor?
Also, while messing with the disty, I noticed that the vacuum canister coming off of it hits the intake, won't let it move any farther counter clockwise. Is that normal?
