This may sound rudimentry and I know it is. I cant remember for anything how to find TDC. I havent timed any of my old vehicles in what I know is too long and I need to do it.
Also. What is the number one cylinder on a 302?
I have 3 different engines to do and I am off for the next few days so I thought I would do them all at once.
One other thing. I just recently got the F100 with the 302. The PO told me that the valves do not need adjusting. Is that right. My f250 is a FE so I am new to the 302.
Thanks Guys

Re: TDC
90% of 302's wont need them adjusted or can't be adjusted anymore. If it's an early motor (pre '68) the rockers should have some adjustment. It's still a hydraulic lifter setup. TDC pop the front passenger side spark plug out, look into the hole to see when the piston comes to the top and then put a screwdriver in the hole to judge TDC (center of piston on top).
Verify the timing pointer to the harmonic balancer and you should be good to go. You can also check that one end of the distributor rotor is pointing at #1 cylinders plug wire to make sure the timings close enough to run.

Re: TDC
Be careful though, the timing marks on the ballancer are at TDC at both the top of the compression stroke and the top of the exhaust stroke. That can kinda screw ya up sometimes.
Best to check that both valves are closed by removing the valve cover, and watching #1 cylinder's valves ~OR ~
By putting your finger over the #1 spark plug hole to feel the compression at the compression stroke, then line up the timing marks to TDC.
The picture below should help you out with cylinder numbering....
