LOL thanks for the reply Patrick. I was a Chevy guy for years in Drag Racing and never had any problems with timing until I switched to Ford
. Geesh, 10 o'clock, 11 o;clock, 2 o'clock, blank timing tabs, pre 1970, post 1974, big block, small block, 28oz., 50oz. Its been a learning experience but I have my dream car and I am having a blast. My tab has a curved outer edge on the bottom side and a flat square edge on the top. I finally call a local Ford shop that has good mechanics that have been there along time. The guy I spoke to knew exactly what I was talking about. He said don't read the bottom with the rounded outer edge. Read the top.
