Crank gear dot should point stright up / 12o clock with #1 pistion at TDC.
all the way up at the top of #1 cylinder.
The cam gear dot should point stright down At 6o clock. That will make both dots stright over top of each other. Then the crank and cam will be in time.
On the front of the timing chain cover, drivers side towards the top of the harmonic balancer.
There is a mark on the timing chain cover behind the harmonic balancer(behind the crank pulley). The harmonic balancer also has a slot cut in it so that you can line the crank up with the mark on the timing cover. The mark on the timing cover should sit at the 2 o'clock position or the 12 o'clock position. My 96 Chevy 305 is at the 2 o'clock position.
It could be your off a tooth with your distributor
what are the timing marks on a chev 305 motor for the year 1995.
Does it turn over? Does it have spark? Does it have fuel? Does it have compression?
a Chevy 350 crank is a Chevy 305 crank. they have the same stroke, 3.48 inches, and are interchangable. swapping between the two cranks does not change the engines displacement
you have to take off the timing chain cover and replace the seal in the timing chain cover as welll youll need the oil pan seal
if you look behind the water pump straight down u can see the timing marks.

There is no timing belt on a 305 unless it is an aftermarket belt drive system.
That requires an OBDII engine scanner to do that.
same as a 350
