I learn something most every day. I have owned a few 340 cars and engines and have never had timing marks on the right side of the cover. My 69 Swinger I had in 1974 had the marks on the left side. I installed a 318 in a 65 Valiant for my high school days and the timing marks were cover'd up by the water pump that I took off the 273.
Thanks for teaching a old Dog new tricks.
It's so good to see the early A's being brought back to life.
