Really stupid question. left vs right cam
Okay,
I'll surely win the dumb question of the day award with this ![]() In the rebuild book figure 6-5 clearly shows the left cam as having lobes that form a very wide V, while the right has a close V lob config. However, which is the left and right side of the engine. My guess is that left/right is from the rear of the engine, there fore left is 1-2-3 and right is 4-5-6. But I want to make sure it isn't left right from the front (flywheel) side of the engine. Thanks, Pat |

Yes, the 123 side is the left side.

from the BA book: The wide lobed cams make a V or an L for left and the narrow lobed cam looks like rabbit ears, R for right.

The intro to the Rebuild book goes over the nomenclature of what is considered left/right and front/back. Take a look at page 6...

Just to follow on from what was titled a silly question.........what would happen if the cams were put in on the wrong sides? Valve to piston contact?

I belive it would try and run backwards.

Technically yes, the engine would try to run backwards, which would tie up the chains, and would be impossible anyways, considering the distributor would be miswired...
