Red motor will have one centre bolt on the head/manifold. Blue and black will have two. Plus they went metric on the block about black motor. It won't say 308, it will say 5.0.
There is two top dead centres per complete 4 strokes. Only one is compression stroke. The other is exhaust stroke. The timing marks will only line up when top dead centre is on the compression stroke. Set the distributor so it's pointing to number one plug lead then.
