It is the second cylinder from the front on the left bank (driver's side of the "V")
The firing order is 1,8,4,3,6,5,7,2 with 1,3,5,7 on the left bank and 2,4,6,8 on the right bank. The distributor turns clockwise.
It is the middle cylinder on the passenger side. With few exceptions the number one cylinder is the farthest one forward. If you look closely on your 4.3 you'll see that the driver side (left) cylinder bank is slightly forward compared to the right bank. On a Chevy they are numbered back and forth from left to right. So, the left bank is numbered 1,3,5 and the right bank is numbered 2,4,6. Hope this helps.

Right Front Cylinder.
#1 cylinder is on the left of the engine as you are facing it from the front.
The 305 is a small black Chevy in the gmc truck. So yes it has a right and left bank = 2 heads one on the right and one on the left...
Cylinder #5 is the middle cylinder on the front or left bank.
most gm v8 that vintage use 18436572 firing order. 65 3 7 4 2 81 The order should look about like the above if it comes out right. The number 1 should be front side toward the left bank (driver side). #1 is left front cylinder.
cylinder 5 is on the left side of the engine, 1 is in front followed by 3, 5, 7. it will be the third one back, right side has the 2,4,6,8 from front to back .
stand at the front of the engine. the cylinder head at your left is actually your right bank, and the head at your right is labled as your left bank, as if you were to label them in reference from the position of being seated in the truck. but for simplicity I will give you reference from the perspective of standing in front of the truck, facing the engine, because that is the way you will be working on it.On the left bank, or the cylinder head at your right, the cylinder closest to you is Number 1 Cylinder. The next one back on the same head is Cylinder Number 3. And the left bank Cylinder closest to the firewall, furthest from you, is Cylinder Number 5.Let's go to the right bank, or the cylinder head at your left standing in front of the motor. The Cylinder closest to you is #2, then #4, and the cylinder furthest from you on this head, closest to the firewall, is then #6.So, the most important aspect of the answer: the firing order is very simple! This is your firing order. 1-2-3-4-5-6
1-8-4-3-6-5-7-2 #1 cyl is first on left bank.
