Re: Need help with my first 350 sbc

Tdc compression for #1 the dots are both at 12 o’clock.

Where the dots are has been a very long time confusement for new engine builders.
I believe it was set up like that by the factory only for accuracy and time/money savings during Engine assembly. Much easier to eyeball two dots close togethor than six inches apart.
Or maybe it was the design engineer thinking he might screw with the minds of novice motor builders for the next 70 years!
