Compression or exhaust stroke
Know this is an old thread but I'm doing a cam install myself and had the same question. Before removing the original cam the only way I could get the crank timing mark in the 12 o'clock position and the cam timing mark in the 6 o'clock position with the number 1 cylinder TDC was on the exhaust stroke. Everything I've read about TDC says it should be on the compression stroke. When I do that, both timing marks are at the 12 o'clock position. Seems like if I install the new cam with its timing mark in the 6 o'clock postion it would be 180 degrees off. Really don't want to mess this up.
