Spark plug gap for a '75 350 please...
I have asked before but could not find the thread. I have a '75 350 bored .040 over. I have a '69 pickup and thats what I "assumed" the engine was. I got the block and head numbers and it came up to be a '75. When I thought it was a '69 the guys at Autozone said the gap was 35 and for the '75 it is 60 if I remeber correctly. Any help would be appreciated.
