Where is TDC of number one? I'm doing a H/C swap and I need to determine the correct push rod length to order. The number one piston is the first piston (if I'm looking at the block) on the driver side correct? And TDC would be when when both the crank timing mark and cam timing mark are at 12:00 correct?
Yes, first on driver's side. Drop a pushrod down the intake lifter hole, put your finger on it so it will go back down (no valve spring so you need to push the lifter to keep contact with cam). When pushrod goes down (intake closes) bring piston to top and you will be at TDC. I thought you had the timing cover on already.
