Old Tune -up Gauge with instructions
 

Bob Carriere asked me to post these pics, they contain
tune up info that we can all use to get the most out of our
engines, especially the Chevy sixes that are hard to time!
Cheers

I should mention this gauge is just a vacuum gauge,
but this does tell us how to tune with any vac gauge

Relocating Timing Mark on Chev Six
 

Hi Guys

In the past we have discussed the problems of using a timing light on Chevy Six - I've relocated the timing marks on my engines to a position that you can actually see. See earlier post http://www.mapleleafup.net/forums/sh...5&postcount=10

Simple and easy and makes timing much easier. Next time I'm checking the timing on one of the engines will have to try the vacuum gauge approach and see how it compares to timing light.

Cheers Phil
