Sorry, I was over-reacting to threads where the guy wants this forum to tell him whether he's got his timing belt on right, but he doesn't want to actually take off his valve cover & look.

If a DOHC engine has both cams off the same direction, same amount (say 1 tooth); its just like an SOHC engine being off 1 tooth. That's not very far off, performance will be degraded, but it can still run.

Normally you would advance or retard your cams to move the power peak up or down in revs. Not necessarily as far as one whole tooth, but you'll need adjustable cam sprockets to play with adjustments smaller than one tooth. So I think it can act just like you're saying.

My only first-hand experience was on a '82 VW (SOHC) that skipped a couple teeth. The camshaft was off maybe 3 teeth. The engine idled quite nicely, but it ran out of breath by 2000 rpm. Even with the clutch disengaged I couldn't rev it over about 2500. In other words, it really sucked, but that was more than 1 tooth.

ps...
I don't think I would have made such a wise-ass answer if your first post had that kind of detail. But I still think if you even suspect your cam timing is off, you're better off re-checking it instead of asking here. There are other things that can also cause the trouble you describe, & your first thing should be to verify your cam timing to rule it out as a possibility.
