Small block Chevy? V8 ?
Of course the cam is only turning half the speed of the crank on this motor.
I always install the timing chain when the #1 cylinder is at TDC on the compression stroke with the distributor pointing to #1.
if memory serves my right since the crank is bigger than the cam the ratio difference would mean that the cam spins faster its late so I could just be not thinking enough but think about the ratio of a rear the smaller pinion turns a one speed while the ring then multiplies that speed to get your ratio.

It does seem to be an interference engine. I did a lot of playing with cylinder #1 and it doesn't matter where I rotate the cam to, the cylinder never seals up. It's not my daily driver fortunately. I also have a '90 Chevy 1-ton that I'm driving now. It's stronger, newer, nicer and gets better mileage. I just liked the square body. It was big and noisy and a lot of fun. It was old and ratty so I didn't have to worry about getting it dirty or banging it up. This sucks.
