I thought that the vacuum might have to be hooked up to manifold... The advance still gets hooked to ported correct?
Thanks for the idea to scribe the lines! Makes it much more simple and easier to read Im sure.
Just to be sure Im using a 318 timing cover with the timing marks cast into the cover and it reads. 10*BTDC, 0, 10*ATDC. With the before being towards the top of the engine or just under the water pump. That cover will still work correct?
